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

Good morning temperature is -15° but the afternoon the temperature raises by 20° right in addition expressions for the afternoon temperature vent to shoulders and find the temperature in the afternoon
Answer:
+ 5°
Step-by-step explanation:
Given,
Good morning temperature = -15°
Raise in temperature = 20°
Afternoon temperature = -15° + 20°
= + 5°
Hence, temperature in after noon is equal to + 5°.
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.

Answer:
x is equal to seven.
Step-by-step explanation:
To solve this you can move like terms to each side, then divide both sides by the coefficient of x:
4 + 6x = -3 + 7x
6x -7x = -3 - 4
-x = -7
x = 7

Step 1: Define
[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 :

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

Step-by-step explanation:
transforming quadratic graphs
Answer:
f(x) = 3(x - 2)² + 4
OR
f(x) = 3x² - 12x + 16
Step-by-step explanation:
Vertex form of a parabola:
y = a(x - h)² + kStandard form of a parabola:
y = ax² + bx + cLet's find the vertex of this parabola.
(h, k) → (2, 4)In order to find the a-value (vertex form), let's use another point besides the vertex on the parabola.
Using (3, 7) for (x, y), let's substitute this point and the vertex (2, 4) for (h, k) into the vertex form equation and solve for a.
7 = a[(3) - (2)]² + 4Simplify using PEMDAS.
7 = a(1)² + 47 = a + 4Subtract 4 from both sides.
a = 3Now we have (h, k) and a of the vertex form.
y = a(x - h)² + k → y = 3(x - 2)² + 4In order to convert from vertex to standard form, simplify the equation by FOILing.
y = 3(x - 2)² + 4y = 3(x² - 4x + 4) + 4Distribute 3 inside the parentheses.
y = 3x² - 12x + 12 + 4Combine like terms.
y = 3x² - 12x + 16Therefore, we have the answer:
Vertex form:
f(x) = 3(x - 2)² + 4Standard form:
f(x) = 3x² - 12x + 16Consider 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
Which operation should you do first when you simplify the expression below?

Answer:
I would assume you would use PEMDAS? thats what I would use
Answer:
Solve the parenthesis
Step-by-step explanation:
In the order of operations (PEMDAS), you would solve what's in the parenthesis first. So you would add 5 and 4, then multiply that by 3 to get the correct answer. Hope that helps!

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 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

On a coordinate plane, point AS
located at(74) and point Bis
located at 8.41 What is the
distance between the two points?
Answer:
√1370 or about 37.01
Step-by-step explanation:
use distance formula
√(x2-x1)^2+(y2-y1)^2
sqrt(8-7)^2+(41-4)^2
sqrt(1)^2+(37)^2
sqrt 1+1369
sqrt 1370
= about 37. 01
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

Can anyone help
Answer:
Answer:
x=3
Step-by-step explanation:
7−3x=−x+1
Step 1: Simplify both sides of the equation.
7−3x=−x+1
7+−3x=−x+1
−3x+7=−x+1
Step 2: Add x to both sides.
−3x+7+x=−x+1+x
−2x+7=1
Step 3: Subtract 7 from both sides.
−2x+7−7=1−7
−2x=−6
Step 4: Divide both sides by -2.
−2x
−2
=
−6
