Meryl needs to cut down 10.5 trees for every 5 cabins she builds. how many trees will she need to cut down if she builds 7 cabins?

14.7 trees

Step-by-step explanation:

First you need to find how many trees she cuts down to build one cabin. So you divide:

10.5/5=2.1

She cuts down 2.1 trees to make one cabin.

Next you multiply:

2.1*7=14.7

2x^2+5x+17

your welcome. : )

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
