Answer:320ft^2
Step-by-step explanation:
80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area
Average rate of change of the function 
Solution:
Given function:
from x = 1 to x = 5
Substitute x = 1 and x = 5 in f(x).


Let us find the average rate of change of the function.
Average rate of change

Here a = 1 and b = 5.

Substitute f(5) and f(1).



Average rate of change of the function 
Answer:
x=10
y=-10
Step-by-step explanation:
multiply first row by 7
14x−21y=350
7x+8y=−10
multiply second row by 2
14x−21y=350
14x+16y=−20
subtract the first row by the second row
−37y=370
solve for y
y=−10
substitute y=-10
14x−21×−10=350
solve for x
x=10
and thats your answer
x=10
y=-10
