Exercise 11 Page 379

Be careful with negatives when distributing.

- 15 + 3b

Practice makes perfect

We are asked to rewrite the given expression using the Distributive Property. To do so, we need to distribute - 3 to the terms inside the parentheses.

- 3(5-b)

DiffToSum

a-b = a+(- b)

- 3[5+(- b)]

Distr

Distribute - 3

- 3(5) + (- 3)(- b)

MultNegNegTwoPar

(- a)(- b)=a* b

- 3(5) + 3(b)

Multiply

- 15 + 3b
