Question

You must find the area of the shaded region in the link below

Answer 1

5x^2 - 20x - 31

Explanation:

2x +3(4x-5) = 8x^2 + 2x - 15

3x + 2(x - 8) = 3x^2 - 22x - 16

8x^2 + 2x - 15 - 3x^2 - 22x - 16 = 5x^2 - 20x - 31

The shaded region is 5x^2 - 20x - 31

Answer 2

5x+1

Explanation:

2x+3

*4x-5

=8x-15

Now you find the area of the white region

3x+2

*2-8

=3x+16

Now you subtract

8x-15

-3x+16

=5x+1
