Greatest Common Factor Find the GCF of the given expression: 4x2+28x When providing your answer, do not add any unnecessary spaces. Example: 2(x-1)
Answer:
4x(x+7)
Step-by-step explanation:
Both 4x^2 and 28x are divisible by 4x, which is also the GCF. This means you just have to divide the different parts of the expression to get 4x(x+7)
The Greatest Common Factor of the given expression 4x² + 28x will be 4x.
What is the greatest common factor?Simply said, it is the biggest common element. The highest consistent element in the above example is 15, making 15 the greatest common factor amongst 15, 30, and 105. The biggest chunk of the common factors is called the "Greatest Common Factor" (of two or more numbers).
The expression is given below.
⇒ 4x² + 28x
Take common 4x from both the terms, then we have
⇒ 4x² + 28x
⇒ 4x(x + 7)
The Greatest Common Factor of the given expression 4x² + 28x will be 4x.

HELP 80 POINTS DUE SOON
Answer:
a = 1
Step-by-step explanation:
The important point here is that both lines are horizontal reflections of each other. If we treat the line x = a as a kind of "mirror" for these lines, every point at the same y value on each line is going to be an equal horizontal distance from that "mirror". If that's confusing, think about how, as you pull your hand away from a mirror, your hand's reflection seems to go deeper into it. As you bring it closer, your reflection gets closer too. And when you're touching the mirror, it seems like your hand and its reflection are touching!
We want to find that "touching" point for the two lines, the intersection, because it'll tell us exactly where our "mirror" - more commonly called the axis of symmetry - is. The point of intersection of any two lines is the point where their equations are exactly equal to each other.
Our equations are y = 3x - 5 and y = 1 - 3x, so setting those two equal to each other and solving for x:
[tex]3x-5=1-3x\\6x=6\\x=1[/tex]
This tells us that the two lines intersect at x = 1, which is exactly our axis of symmetry, so a = 1!

Step-by-step explanation:
I really hope this helps, if not I am so sorry
Answer:
G= 1/6p -15
Step-by-step explanation:
Let's solve for g.
p=6g+90
Step 1: Flip the equation.
6g+90=p
Step 2: Add -90 to both sides.
6g+90+−90=p+−90
6g=p-90
Step 3: Divide both sides by 6.
6g/6 = p−90/6g
=1/6p−15

Absolute value is basically:
A. A number's distance from 0 on a number line
B. The greatest number on a number line
Answer:
A because absolute value doesn't change the actual value of the number, just makes it positive no matter what, but it's still the same distance from 0, just in the opposite direction.
Step-by-step explanation:
Answer:
A : a number distance form 0n the number line
Step-by-step explanation:
ex: if you want to find the absolute value of -4 you would look at the distance from zero so it would be 4 from zero so the absolute of -4 is 4

Answer:
50 degrees
Step-by-step explanation:
Since the two lines are parallel, we know that the other angle above angle 1 is also 130, because corresponding angles are congruent. Next, since we know that it sits on a line, we know that angle 1 and 130 make a linear pair, or add up to 180 degrees. 180-130= angle 1. So angle 1 is 50 degrees. Sorry if the explanation is a bit funky.
The lengths of the sides of a triangle are in the extended ratio 4 : 7 : 8. The perimeter of the triangle is 95 cm. What are the lengths of the sides?
Answer:
20 cm, 35 cm, 40 cm
Step-by-step explanation:
sum the parts of the ratio, 4 + 7 + 8 = 19 parts
Divide the perimeter by 19 to find the value of one part of the ratio.
95 cm ÷ 19 = 5 cm, then
4 parts = 4 × 5 cm = 20 cm
7 parts = 7 × 5 cm = 35 cm
8 parts = 8 × 5 cm = 40 cm
Thus the 3 sides are 20 cm, 35 cm and 40 cm
Answer:
The measure of the sides of a triangle will be:
4x = 4(5) = 20 cm
7x = 7(5) = 35 cm
8x = 8(5) = 40 cm
Step-by-step explanation:
Given that the lengths of the sides of a triangle are in the extended ratio 4 : 7 : 8.
Also given that the perimeter of the triangle is 95 cm.
We know that the Perimeter of a triangle is the sum of all the sides of a triangle.
As the lengths of the sides of a triangle are in the proportion 4 : 7 : 8. Thus, the measure of the sides will have the same scale factor x.
Therefore,
4x + 7x + 8x = 95
Add similar elements: 4x + 7x + 8x = 19x
19x = 95
Divide both sides by 19
19x/19 = 95/19
x = 5
Therefore, the measure of the sides of a triangle will be:
4x = 4(5) = 20 cm
7x = 7(5) = 35 cm
8x = 8(5) = 40 cm
Verification:
20 + 35 + 40 = 95
95 = 95
To rent a certain meeting room, a college charges a reservation fee of $34 and an additional fee of $9.30 per hour. The math club wants to spend less than $99.10 on renting the meeting room.
What are the possible amounts of time for which they could rent the meeting room?
Use t for the number of hours the meeting room is rented, and solve your inequality for t.
Answer:
9 hours.
Step-by-step explanation:
31 + 5.9*t < 84.10.
To solve it, collect the constant terms on the right side:
5.9*t < 84.10 - 31 = 53.10,
Hence, t < 53.10%2F5.9 = 9 hours.
Answer:
7 hours
Step-by-step explanation:
99.10-34=65.1
65.1 divide by 9.30=7

My wife baked cookies this year. 40% of the cookies she baked were chocolate chip. If she baked 36 chocolate chip cookies, how many total cookies did she bake
Answer:
She baked 90 cookies.
Step-by-step explanation:
From the information given you know that 36 cookies represent 40% of the cookies that were baked. With this information, you can use a rule of three to find the total mount of cookies that she baked:
36 cookies → 40%
x ← 100%
x=(36*100)/40=90
According to this, the answer is that she baked 90 cookies.

Answer:
replace recipe quantities:
1/4 ⇒ 5/8; 1/2 ⇒ 1 1/4; 1 ⇒ 2 1/2; 1 1/2 ⇒ 3 3/4; 2 ⇒ 5
Step-by-step explanation:
The given recipe serves 4, so must be multiplied by 10/4 = 5/2 to make it make 10 servings.
The numbers in the recipe (ignoring units or ingredients) are ...
1/4, 1/2, 1, 1 1/2, 2
Each of these numbers needs to be multiplied by 5/2 to get the number for the larger recipe.
1/4 × 5/2 = 5/8
1/2 × 5/2 = 5/4 = 1 1/4
1 × 5/2 = 5/2 = 2 1/2
(1 1/2) × 5/2 = 3/2 × 5/2 = 15/4 = 3 3/4
2 × 5/2 = 5
Then, to make the larger recipe, rewrite it with the quantities replaced as follows:
old value ⇒ new value
1/4 ⇒ 5/8
1/2 ⇒ 1 1/4
1 ⇒ 2 1/2
1 1/2 ⇒ 3 3/4
2 ⇒ 5
__
For example, 1 1/2 lbs of fresh tomatoes ⇒ 3 3/4 lbs of fresh tomatoes
_____
Additional comment
If you actually want to create the recipe, you may find it convenient to use a spreadsheet to list quantities, units, and ingredient names. Then you can add a column for the quantities for a different number of servings, and let the spreadsheet figure the new amounts. (A spreadsheet will compute quantities in decimal, so you will need to be familiar with the conversions to fractions--or use metric quantities.)
What is the mean of the data set? 300, 222, 285, 310, 345. Round to the nearest tenth.
Answer:
292.4
Step-by-step explanation:
Answer:
292.4
Step-by-step explanation:
Use the mean formula: sum of elements / number of elements
Plug in the numbers:
(300 + 222 + 285 + 310 + 345) / 5
1462 / 5
= 292.4
So, the mean is 292.4

find the estimates of x^2-x-2=3
Answer:
[tex]x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79[/tex]
Step-by-step explanation:
Given
Quadratic equation is
[tex]x^2-x-2=3\\x^2-x-5=0[/tex]
Roots of the quadratic equation [tex]ax^2+bx+c=0[/tex] are
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\[/tex]
So, for the given equation roots are
[tex]x=\frac{1\pm\sqrt{(-1)^2-4(1)(-5)}}{2\cdot 1}\\x=\frac{1\pm\sqrt{21}}{2}\\so, x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79[/tex]
The temperature in a town is 34.1°F during the day and -8.6°F at night. Find the difference in the temperatures.
Answer:
the difference is 25.5
Step-by-step explanation:
34.1 - 8.6 = 25.5
[tex]42.7^{\circ}F[/tex]
Subtract the number with the smallest value from the number with the biggest value to determine the difference between two numbers.
Temperature in a town during the day [tex]=34.1^{\circ}F[/tex]
Temperature in a town during the night [tex]=-8.6^{\circ}F[/tex]
Therefore,
Difference in temperatures [tex]=34.1-(-8.6)[/tex]
