Question

Select True or False.

Answer 1

Answer:

True

Step-by-step explanation:

5x − 3(2x − 4)

Expand

5x - 6x + 12

-x + 12

12 - x

( ) are called "parentheses" or "brackets "

Whatever is inside the ( ) needs to be treated as a "package".

So when multiplying: multiply by everything inside the "package".

Multiplying negatives has special rules: a negative times a positive gives a negative, but multiplying two negatives gives a positive:

In that case −3 · -5 = +15 (a positive answer)

Answer 2

Answer:true

Step-by-step explanation:

5x-3(2x-4)=

1) solve the parentheses

5x-6x-12=0

2) we just can rest the X

5x-6x=X

3) X-12=0

4) The order of factors does not alter the product

12-X=0
