Arectangle has a perimeter of 71.8 yards and a height of 3.3 yards. what is the length of the base?

The length of the base is 32.6

3.3 + 3.3 = 6.6

Subtract 6.6 from 71.8 : 65.2

Divide that by 2 : 32.6

32.6 I think. I took the height, multiplied it by 2 (because there are to sides that is that length) and then subtracted it by 71.8 to get 65.2, lastly I divided it by 2 for the same reason (there are two sides the same length).

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
