Practice makes perfect

We are asked to evaluate the given expression using the Distributive Property. To do so, we need to distribute - 5 to the terms inside the parentheses.

(12-4)(- 5)

a-b = a+(- b)

[12+(- 4)](- 5)

Distribute - 5

12(- 5)+(- 4)(- 5)

a(- b)=- a * b

- 12(5)+(- 4)(- 5)

MultNegNegTwoPar

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

- 12(5)+4(5)

Multiply

- 60 + 20
