Step-by-step explanation:
20^2 because you are multiplying 20 two times
20×20=20², is the exponent form.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
Here, we have,
20×20
=400
=20²
Hence, 20×20=20², is the exponent form.

Surface area question:
Answer:
190π (not part of the answer choices)
Step-by-step explanation:
The surface area of a cylinder can be found using the formula below:
[tex]SA=2\pi r^2+\pi dh[/tex] where [tex]r[/tex] is the radius of the base, [tex]d[/tex] is the diameter of the base and [tex]h[/tex] is the height of the cylinder.
Plug in the given values
[tex]SA=2\pi (\frac{10}{2}) ^2+\pi (10)(14)\\SA=2\pi (\frac{100}{4})+140\pi\\SA=2\pi (25)+140\pi\\SA=50\pi+140\pi\\SA=190\pi[/tex]
Therefore, although this answer isn't one of the choices, the surface area of the cylinder is 190π.
I hope this helps!

If x = 8 units, y = 3 units, and h = 1 unit, then what is the area of the parallelogram shown above?
Answer:
8unit²
Step-by-step explanation:
The Area of a parallelogram :
Length of base * height
Length of base, x = 8 units
Height, h = 1 unit
Area = Length of base * height
Area = 8 units * 1 unit
Area = 8unit²
Help me please this is my homework question
512 c2 so A sorry if im wrong
Answer:
384
Step-by-step explanation:
So there are 6 faces in a cube so first you need to know how big is one face then just multiply by 6 for all 6 faces. so 8*8 = 64. that means 64 is the area of one face.
then multiply that by 6 to get the total surface area.
there it is your answer 384 the 3rd option there
if ABC is similar to DEF, determine the measure of A
Answer:
the answer is 66°
Step-by-step explanation:
As it is given that triangle ABC is similar to triangle DEF so
< A = < D ( being corresponding angles of similar triangles)
3x + 18° = 4x + 2°
4x - 3x = 18° - 2°
x = 16°
So now
< A = 3 * 16° + 18° = 66°
-12x + 4y- 6y + 10x - 25 5x - 2(x - 12)
Answer:
=−259x−2y+24
Step-by-step explanation:
Distribute:
=−12x+4y+−6y+10x+−255x+(−2)(x)+(−2)(−12)
=−12x+4y+−6y+10x+−255x+−2x+24
Combine Like Terms:
=−12x+4y+−6y+10x+−255x+−2x+24
=(−12x+10x+−255x+−2x)+(4y+−6y)+(24)
=−259x+−2y+24
Answer:
=−259x−2y+24

8x−20
Apply the distributive property to factor out the greatest common factor.
Answer: 4(2x - 5)
Step-by-step explanation:
factors of 8 : (2, 2), 2
20 : (2, 2), 5
Therefore the GCF is 2*2 = 4
8x/4 = 2x and -20/4 = -5
4(2x - 5) = 8x - 20

Answer:
slope is 15/5=3
Step-by-step explanation:
1. Find the slope and the y-intercept
of the graph of the linear equation.
y = -7x + 2
A) slope: -3; y-intercept: 2
1
B) slope: 2; y-intercept: -7
C) slope: -7; y-intercept: 2
D) slope: 2; y-intercept: -7
Answer:
c) slope: -7 ; y-intercept: 2
Step-by-step explanation:
Note the slope intercept form:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
Note in this case:
y = (-7)x + 2
y = y
m = -7
x = x
b = 2
c) slope: -7 ; y-intercept: 2 is your answer.

Answer:
C.) 10,240 cubic feet
Step-by-step explanation:
We have to first find the area of the base by multiplying 32 by 32. 32 * 32 is equal to 1024. Next, we multiply by the height divided by 3. 30/3 is equal to 10, so the total volume is equal to 1024 * 10, which is 10240.

What is the value of X
Answer:
11=x
Step-by-step explanation:
since the lines are parallel the distances between each section of line is proportional to each other.
5/6=(x-1)/12
multiply both sides by 12
12(5/6)=(x-1)12/12
10=(x-1)
add 1 to both sides
10+1=x-1+1
11=x
I hope that helps :)
