It cannot be factored, so it is prime.
To find n
1. Subtract 8n from both side to get -3n=30
2. Divide both sides by -3 to get n=-10
B is the only one that makes sense if you break them each down. An Acute doesnt have every Pair of angles congruent, the don't have to have proportional side lengths, and it can't have a right angle or it would be a right triangle.
2a.) 8.8 x 8.8 = 35.2g
2b.) 35.2 x 30 = 1056g or 1.056kg
There the answer is A the range is none negative
