Answer:
6x^2+17x+9
Step-by-step explanation:
you have to subtract the area of the white rectangle from the area of the entire rectangle
to find the area of the inner rectangle do (2x-3)*(x+1)=2x^2-3x+2x-3=2x^2-x-3
to find the area of the entire rectangle do (4x+6)*(2x+1)=8x^2+12x+4x+6=8x^2+16x+6
(8x^2+16x+6)-(2x^2-x-3)=8x^2+16x+6-2x^2+x+3=6x^2+17x+9

Answer:
3 ≤ y
Step-by-step explanation:
-4(y-6) ≤ (-9+y)(-2)
Distribute
-4y +24 ≤ 18 -2y
Add 4y to each side
-4y+4y +24 ≤ 18 -2y+4y
24≤ 18 +2y
Subtract 18 from each side
24-18≤ 18-18 +2y
6 ≤ 2y
Divide by 2
6/2≤ 2y/2
3 ≤ y
