Use the graph of f to estimate the local maximum and local minimum.
a.) local maximum: infinity; local minima: -2 and 2
b.) local maximum: 0; local minima: -2 and 2
c.) no local maximum; local minimum: -4
d.) local maximum: 0; local minimum: -4

answer:

c. the third graph

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
