Homework Help: Math

Posted by Gertrude Sanders on Wednesday, November 5, 2008 at 11:30am.

I want to know did I work these problems right

Multiply: ( - 6)² - 4² = 36 – 16 = 20

Multiply
( - 3) ( - 6 ) + ( 4 ) ( -2) = 18 + ( -8) = 18-8= 10

Multiply: ( - 3 ) ³ - ( - 8) ( -2) =
(-3) times 3 = -9
(-8) times (-2) = 16
-9 - 16 = -25

-25

Multiply: -9 ² - ( -6)² = 81-36= 45
