3. If f(x) = 5x^2 find i) f(3)×f(2) and find x if f(x) = 2.

mark as brainliest and a like

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

the answers might not be correct use at own risk

i believe that the answer is

b. y-1=-2(x-4)

hope this !
