Exercise 41 Page 228

Begin with the Distributive Property.

64v

Practice makes perfect

To simplify the given expression, we will use the Distributive Property.

2(5v+6)-6(-9v+2)

Distribute 2

2(5v) + 2(6) -6(-9v+2)

Distribute -6

2(5v) + 2(6) + (-6)(-9v)+ (-6)2

Multiply

10v + 12 +54v -12

CommutativePropAdd

Commutative Property of Addition

10v+54v+12-12

Add and subtract terms

64v

As there is now only one term, our expression cannot be simplified any further. Therefore, 64v is the difference we were looking for.
