Which function models the area of a rectangle with side lengths of 2x – 4 units and x + 1 units?

f(x)=2x²-2x-4

Step-by-step explanation:

f(x)=(2x-4)(x+1)

f(x)=2x²-2x-4

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

10 b/c 5*2 =10
