Can 8,7, and 8 make a triangle?

Yes!

Step-by-step explanation:

In order to make a triangle, the sum of two sides must be larger than the third side or the largest side.

a+b>c

so 8+7>8

you could also do b+c>a , or a+c>b

even if you chose to use 8+8>7, it would still work

I might be wrong, but I'm a little confident lol. I hope I helped a bit :0

where's the diagrams?

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
