[2 × (24 ÷ 3)] + 7
Step 2: Evaluate
[Brackets] (Parenthesis) Divide: [2 × 8] + 7[Brackets] Multiply: 16 + 7Add: 23Answer:
→ [2 × 24/3] + 7
Divide 24 by 3 we get 8 as the product:
→ [2 × 8] + 7
Now, multiply 8 by 2 we get product as 16 :
→ 16 + 7
Let's add the 16 and 7 and we get final answer as :

70x
Step-by-step explanation:
8x8 = 64x then +6x = 70x
Answer:
[tex]2x(4x+3)[/tex]
Step-by-step explanation:
The first thing to factorising this expression is to find the greatest common factor (GCF). For 8x² and 6x the gcf is 2x. So now we divide the 8x² and 6x by the 2x. Which comes out to 4x and 3, these will be inside the parentheses.
So it'll factorise to [tex]2x(4x+3)[/tex] and remember when we are dividing with exponents we subtract the exponents. So [tex]\frac{8x^2}{2x}[/tex] we will divide the coefficients together that'll be 4 and now for the exponents the 2 on the x² minus the 1 on the x will equal 1 so it'll be just x we don't place a one or anything.
What is the value of h(-2) if h(x)=4x^2-x+9?
Answer:
16x² + 2x + 9
Step-by-step explanation:
To evaluate h(- 2x) , substitute x = - 2x into h(x), that is
h(- 2x)
= 4(- 2x)² - (- 2x) + 9
= 4(4x²) + 2x + 9
= 16x² + 2x + 9

Order from least to greatest.
0.387; 0.3; 0.783; 0.837
someone do these please!
Answer:
I think the first option is better.
Step-by-step explanation:
First : 5.75% of $5000 is 287.5. 287.5 * 24 = 6900
And 6.55 of $5000 is 325. 325 * 36 = 117000
If she takes the first option it would be better because it is nearer to what she can afford. It is also better because it helps her make more than 5000 in less time.
HOPE THIS HELPED.

14+x = -9
X equals what?
Answer:
x=−23
Step-by-step explanation:
14+x=−9
Step 1: Simplify both sides of the equation.
x+14=−9
Step 2: Subtract 14 from both sides.
x+14−14=−9−14
x=−23
Answer:
-23
Step-by-step explanation:
14+x =-9
-14 -14
x = -23

Answer:
Step-by-step explanation:
count all the full squares... 12
and add 1/2 a square for the angled one
12.5 :) or 12 1/2
Answer: 12.5 sq units
Step-by-step explanation:
Make two triangles (big and small triangle) and one rectangle. ( kinda like what's in the pic)
Area of big triangle:
b = 3 h = 3
1/2 x 3 x 3 = 4.5 sq units
Area of small triangle:
b = 2 h = 2
1/2 x 2 x 2 = 2 sq units
Area of rectangle:
l = 3 w = 2
3 x 2 = 6 sq units
Area of the figure: A. of rect. + A. of s. tri. + A. b. tri.
6 + 2 + 4.5 = 12.5 sq units

Graph the line with the equation
Answer:
Step-by-step explanation:
Work out the size of angle x.
Answer:
13 degrees.
Step-by-step explanation:
First we calculate the other 2 angles of the triangle of which < x is a part.
The bottom angle = 85 (vertical angles are equal).
The top one = 180 - 98 = 82. ( corresponding and adjacent angles).
So angle x = 180 - (85 + 82).
= 180 - 167
= 13 degrees.
what is the simplified expression for this ?
Answer:
I think it is 14.1421356237. I needed you can round it down to 14.14.
during a field trip 60 students are put into equal sized groups,describe two ways to interpret 60divided by 5 in this context
Answer:
12 students
Step-by-step explanation:
You can just divide 60 by 5 and get the answer, or you could go the longer route and put an amount into each of the five groups until it comes up to 60, then you will have your answer of how many students are in each group.

Step-by-step explanation:
solve 3(y+4) = 24
could you please explain how you found y ^^
Answer:
Answer is 68
y + 4 = 72
y = 68
Next Question!!? Help please... <3
Answer:
x=4 and y=0
Step-by-step explanation:
Sub x-4 in for y:
2x+4(x-4)=8
2x+4x-16=8
6x=24
x=4
y=x-4
y=4-4
y=0
Y = 4
X = 0

what is the area of a circle whose radius is 4x centimeters? write your answer in terms of pi.
Answer:
16xpi
Step-by-step explanation:
To find the area of a circle the formula is pi r squared.
r represents radius, aka 4x.
4 times 4 yields 16.
Leaving you with 16xpi

Consider the line y = - 4x +3,
Find the equation of the line that is parallel to this line and passes through the point (2, -3).
Answer:
y = -4x + 5 {slope-intercept form}Step-by-step explanation:
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
y = - 4x + 3 ⇒ m₁ = -4 ⇒ m₂ = -4
The point-slope form of the equation of a line it's y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.
m = -4
(2, -3) ⇒ x₁ = 2, y₁ = -3
point-slope form:
y - (-3) = -4(x - 2)
y + 3 = -4x + 8 {subtact 3 from both sides}
y = -4x + 5 ← slope-intercept form

There are no real zero in the equation.
Use the expression 14x + 28y + 21
(Answer both questions below)
Part A: What is the greatest common factor of the expression?
Part B: Factor the expression
Answer:
A) 7 is the greatest common factor of the expression.
B) factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]
Step-by-step explanation:
We are given the expression: [tex]14x + 28y + 21[/tex]
Part A: What is the greatest common factor of the expression?
We need to find the greatest common factor of the expression.
The expression is divisible by 7
So, 7 is the greatest common factor of the expression.
Part B: Factor the expression
We need to factor the expression: [tex]14x + 28y + 21[/tex]
Taking 7 common:
[tex]14x + 28y + 21\\=7(2x+4y+3)[/tex]
So, factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]

What single decimal multiplier would you use to decrease by 6% followed by a 7% increase?
Answer:
the single decimal multiplier is 1.0058
Step-by-step explanation:
Let us have 100
Decreasing by 6% will be
100 - 0.06(100)
= 94
Increasing by 7%
= 94 + 0.07(94)
= 100.58
So
to get the single decimal multiplier,
we have 100.58/100 = 1.0058
What is the answer to:
x/-6 -8 ≤ -12
Answer:
x (is greater than or equal to) -24
Step-by-step explanation:
x/-6 - 8 (is greater than or equal to) -12
add 8 to both sides
x/-6 (is greater than or equal to) 4
multiply both sides by -6
x (is greater than or equal to) -24
sorry I didnt know where to find the sign so I just wrote is greater than or equal to

What does the question mark stand for in the following when you factorise:
4d3 + 6de =? (2d2 +3e
Answer:
Question mark stands for 2d
Step-by-step explanation:
Here, we want to get what the question marks stands for
As we can see, the left was factorized to give the right
So, we have that ;
4d^3 + 6de = 2d(2d^2 + 3e)
so the question mark stands for 2d
