Question

Carl simplified 6h-h. He said an equivalent expression was 5h. Do you agree with Carl? A. Agree, because 6h-h can be factored as h(6-1) to simplify it. B. Disagree, because h is a common term in both so h-h is 0, that leaves 6. C. You cannot tell if he is correct because you do not know the value of h. D. Carl is only correct if h is a positive number.

Answer 1

A. Agree, because 6h-h can be factored as h(6-1) to simplify it.

Explanation:

What we will do is operate the expression just like this:

`6h-h=h\cdot(6-1)=h\cdot5=5h`
