because ( (-2)³+8))/(-2+2)=0/0,
you use formula a³+b³°(a+b)(a²-ab+b²).
therefore (x³+8)/(x+2) = ( (x+2)(x²-2x+4))/(x+2) = x²-2x+4
so lim x->-2 (x²-2x+4) = (-2)²-2*(-2)+4=
=4+4+4=12.
17. Subtraction. According to the order of operations, he should've done the exponent of 3 first.
18. He then did 15×2. According to the order of operations, he should've done the multiplication of 8×2, since, if there are only multiplication and/or division left, you work left to right. He isn't correct.
19. 16, I think, I did it in my head.
The Answer is 11.5 because 3•-8=-24+5=-19-4=-23%2 gives you 11.5
The answer is x = 0.5 To get this you do 9-7 which is 2 and then do 2 divided by 4 which is 0.5
