Answer:
<h2>384 yd²</h2>
Step-by-step explanation:
The formula of a surface area of a cube:

We have <em>a = 8 yd</em>.
Substitute:

Answer:
x=-7
Step-by-step explanation:
2x+3=x-4
2x-x=-4-3
x=-7

First notice that

. If

is not a factor of the numerator, then there is a non-removable discontinuity at

, and a removable discontinuity otherwise.
You have

, which means, by the polynomial remainder theorem, that

is indeed a linear factor of the numerator. Dividing yields a quotient of

so the limit is
