Question

Which expression shows the result of applying the distributive property to -3x(5 + 8)?

a. -15x+8
b. -15x-24x
c.-3x-24x
d.-15x - 24

Answer 1

b

Explanation:

(-3x)*(5 + 8)

(-3x * 5) + (-3x * 8)

(-15x) + (-24x)

-15x - 24x

Answer 2

Using the distributive property, we can multiply -3x by each term inside the parentheses:

-3x(5 + 8) = -3x(5) - 3x(8)

Simplifying each term, we get:

-15x - 24x

So the answer is (b) -15x-24x.
