A=w*h
p=2w+2h
if w=x, then h=7-x.
a(x) = x*(7-x)
a(x) = 7x - x^2
to find the largest area we need to derivative a(x):
a'(x) = 7 - 2x = 0 --> x = 3.5
therefore:
maxArea = a(3.5) = 3.5 * 3.5 = 12.25
Answer:
z = -1
Step-by-step explanation:
0 = 8z + 8
-8 = 8z
-8/8 = z
z = -1
check:
0 = 8*-1 + 8
0 = -8 + 8
