#1

-2*(-3)+(2-1^2)^2 =

6 + (2-1)^2 =

6 + 1^2 =

6 + 1 =

7

#2

3(-4t-x)- 6(-5x-6t) =

-12t -3x + 30x + 36t =

24t + 27x =

3(8t + 9x)

#3

S = 2B + Ph

Ph = S - 2B

h = (S - 2B)/P

#4

8(x+6) = -5x + 22

8x + 48 = -5x + 22

13x = -26

x = -26/13 = -2.

#7

-9x + 2y = 25
-3x + 7y = 2

Add (-3) times 2nd equation to the 1st:

-19y = 19
-3x + 7y = 2

Now we have that y = 19/(-19) = -1.

Plug that into the 2nd equation to find x:

-3x + 7(-1) = 2

-3x - 7 = 2

- 3x = 9

x = 9/(-3) = -3.

x = -3 & y = -1.

#8

Im assuming you meant (b^3a^2)/(b^6a^4):

(b^3a^2)/(b^6a^4) = 1/(b^3a^2)
