Answer:
(since they're similar, set them up as a proportion to find x)
14*14 = 8(x+2) (cross multiply, solve the left side, and distribute the right side)
196 = 8x +16 (subtract 16 from both sides)
180 = 8x (divide both sides by 8)
x= 22.5 (is your answer, or C)

Step-by-step explanation:
Significant digits are all digits, after the comma, excluding the first if this first is Zero

For

to be continuous at

, we need to have

Note that

means that

, but that

is *approaching* 5. We're told that for

, we have

We can write

and the limit would be

and so

is discontinuous.
