Answer:
B. 14
Step-by-step explanation:
To determine whether a triangle or not, use the triangle inequality theorem. Two smaller sides must add up and be greater than the larger side.
13+7=20 wouldn't work
14+7>20 would work
7+20=27 wouldn't work
7+20<28 wouldn't work
nonliner
it curves
x=-4
7-x=3
x=3-7
X+4 is prime. X2-9can be factored using the formula
its 8
32 - 8 = 24 and 40- 16 = 24
A = bc(sin A)
