Subtract these polynomials.
(2x^2 + 2x + 3) – (x^2 + 2x + 1) =

2 + 2 i believe this is what your asking for

Step-by-step explanation

The x^2 cancel each other out so your left with 2

the 2x cancel each other out so your left with 3 - 1 = 2

2 + 2

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

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
