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

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
