Question

Evaluate the expression: -3(-5x + 10), when x = -3

Answer 1

-75

Explanation:

Lets do this the easy way!

We do:

P= Perenthasis

E = Exponents

M = multiplication

D = Division

A = Addition

S = Subrtaction

So we do whatevers in the parenthasis first

(-5x + 10)

Now since we know x=-3 since its being multiplied by -5 we multiply!

-5*-3 then add 10

-5*-3+10=25

Then since -3 is touching the paranthasis it means to multiply!

take the answer of the apranthasis problem

25 and times it by -3

Which equals -75

Hope this helps you!

Answer 2

-75

Explanation:

-3(-5x + 10)

Let x=-3

-3(-5*-3 + 10)

Multiply inside the parentheses

-3(15 + 10)

Add inside the parentheses

-3 (25)

-75
