Question

If you combine like-terms, what will the constants be? 3h - 12 + 4h + 4.

A. -12, 4
B. 3, 4
C. -12, 4h
D. 3h, 4.

Answer 1

In the expression 3h - 12 + 4h + 4, combining like terms results in 7h for the variable terms and -8 for the constant terms. The constants present before combining are -12 and 4, making option (A) the correct choice.

Step-by-step explanation:

To combine like terms in the expression 3h - 12 + 4h + 4, we need to combine the terms with the variable h and the constant numbers separately.

The like terms with the variable h are 3h and 4h, and when combined, they give us 7h. For the constants, we combine -12 and +4, which equals -8. Therefore, the constants after combining like terms are -8. The final simplified expression is 7h - 8.

The correct option that represents the constants only is (A) -12, 4, as those are the constants present before combining like terms.
