Answer:
40
Step-by-step explanation:
So far, the Lengths we have are
4, 4, 8, and 4
for the bottom length, add 8 and 4
For the side length, and 4 and 4
so the lenghts are 4, 4, 8, 4, 8, and 12
4+4+8+4+8+12=40
-4,12 if on a coordinate plane would be 4 to the left and twelve down(if not what your looking for for the answer than sorry)
What is it? Put the picture up
Answer:
Step-by-step explanation:
No idea
Each piece of this function is continuous on its respective domain (because all polynomials are continuous functions), meaning
• 2 - x exists for all x < -1
• x exists for all -1 ≤ x < 1
• (x - 1)² exists for all x ≥ 1
So this really just leaves the points where the pieces are split up, i.e. x = -1 and x = 1. At both of these points, the two-sided limit exists as long as the one-side limits from both sides exist and are equal to one another.
At x = -1, as I said in my comment, you have

while

But -1 ≠ 3, so the two-sided limit

does not exist. So a = -1 is one of the points you would list.
At x = 1, we have

while

and again the one-sided limits don't match, so this two-sided limit also does not exist, making a = 1 the other answer.
