Which expressions are equivalent to 6g-18h6g−18h6, g, minus, 18, h?

3(2g-6h)

-2(-3g+9h)

Step-by-step explanation:

We have given the expression:

6g-18h

There are two expression which are equivalent to 6g-18h

Write down the expression first:

6g-18h

3(2g-6h)

This expression is equivalent to 6g-18h

Then,

6g-18h

Take -2 as a common. Then we have:

-2(-3g+9h)

If you multiply the values inside the bracket by -2 you will get the same expression as 6g-18h

15

step-by-step explanation:
