Hello, I received a math packet on things I never learned and was hoping you can help me.

Multiply:

1) 8(x+2)=

2) -5(2a+3b)=

3)(x+2)(x+3)

4)2a(b+3c-4d)=

5)a-(2a-4)=

6) -2(x+3)- 7(2x-3)=

7) 3d-7-(5-2d)=

solve each equation or inequality:

8) 5x-2+3x=2x+6-4x

9)-4x-7>-35

simplify each of the following:

10) (3y)^{2}=

11) 3^{3}x5^{2}=

12) (x^{5 }y^{2})^{3}=
