Subtract these polynomials. (3x2 – 2x + 5) – (x2 + 3) = a. 2x2 – 2x + 8 b. 4x2 – 2x + 2 c. 4x2 – 2x + 8 d. 2x2 – 2x + 2

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
