Answer: 22-4x when you simplify it all.
(20 + 12) - 8, since the question states n is EIGHT less than the sum of 20 and 12.
Answer:
18
Step-by-step explanation:
The dimensions that would result to maximum area will be found as follows:
let the length be x, the width will be 32-x
thus the area will be given by:
P(x)=x(32-x)=32x-x²
At maximum area:
dP'(x)=0
from the expression:
P'(x)=32-2x=0
solving for x
32=2x
x=16 inches
thus the dimensions that will result in maximum are is length=16 inches and width=16 inches
you can work it out or put in random numbers until the two sides are equal
