Hello!
We know what the base and area of the parallelogram are, but the height is still unknown. We also know that the formula for the area is:
A = bh
Meaning we multiply the base by the height to find the area. The opposite of multiplication is division, so we must divide the area by the base to find the height. (We work in the opposite way).
B = a / h
B = 700 cm² / 35 cm
B = 20
We can double check by multiplying 20 by 35, and the product should result in 700.
20 * 35 = 700
Therefore, the height of the parallelogram is 20 centimetres.

Answer: 75.36 square feet</h3>
Your teacher may want you to type the number only.
==========================================================
Work Shown:
SA = surface area of a cylinder
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*2^2 + 2*3.14*2*4
SA = 75.36
The surface area is roughly 75.36 square feet.
Answer:
A
Step-by-step explanation:
You find the mean by adding all the values then dividing that sum by the amount of values
You find the median by putting the numbers in order from least to greatest and then find the middle number.
Let "a" and "b" be the two numbers
So a*b=-8 and a+b=-7
Therefore S=-7 and P=-8
Using (x^2)-S+P=0 => (x^2)-(-7)+(-8)=0 => (x^2)+7-8=0
By factorizing we get (x+8)(x-1)=0
So a can be either -8 or 1 and b can be 1 or -8
Meaning that the two numbers are -8 and 1.
