The expression 5x - 3 (2x - 4) is equivalent to the expression 12 - x.

True

False

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: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
