Answer 1

Answer 2

Area is found by:

\(\large\bf{A=b \times h}\) This means you need to find the area of both the shaded region and the unshaded region by means of the formula.

\(\large\bf{A=(2x +2) \times (3x-4)}\)
\(\large\bf{A=(x-3) \times (x-6)}\)

Can you simplify those?

Answer 3

6x^2-2x-8 for the 1st one?

Answer 4

yep

Answer 5

and x^2-9x+18 for the 2nd one?

Answer 6

Correct.

Now you just need to subtract the two.

Answer 7

12x^3-x^2-9x+10

Answer 8

Not quite.

\(\large\bf{(6x^{2}-x^{2}) - (2x - 9x) - (8+18)}\)

Answer 9

5x^2+7x-20

Answer 10

close the last term would be 26.

\(\large\bf{5x^{2} + 7x - 26}\)
