Add together the products
Answer:
175 square feet
Step-by-step explanation:
the area of the whole thing is 400 ft. (20 x 20=400)
i got the 20 from the perimeter b/c 20+20+20+20=80
then subtract the area of the pool from 400 to get 175.
The similar paperweight has a volume of 67.2 cubic cm if the height is 7 cm.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
As we know,
Volume = base area×height
38.4 = base area×4
base area = 38.4/4 = 9.6 square cm
A mathematically similar paperweight has a height of 7 cm.
Volume = base area×height
Volume = 9.6×7 = 67.2 cubic cm
Thus, the similar paperweight has a volume of 67.2 cubic cm if the height is 7 cm.

Step-by-step explanation:
f(x) = x² - 7x+5 and g(x) = - 4x
(fog) (x) = (-4x)² -7(-4x) +5
= 16x² +28x +5
(fog)(2) = 16(2)² +28(2) +5
= 64 +56 +5
= 125
