The problem statement asks for the area of the pool. We will assume that is an error, and that you want to fill in the table with the area of the walkway.
Consider a walkway of width w. The outside dimension of the walkway will be 2w plus the dimension of the pool (since there is a walk on either side). Thus, the outside dimensions of the pool and walkway are 9+2w and 12+2w yards.
The area of the pool and walkway will be
... total area = pool area + walkway = (9 + 2w)(12 + 2w) = 9·12 + 2w(9+12) +4w²
... total area = (9·12) + walkway = 9·12 + 42w + 4w²
Subtracting the pool area gives the area of the walkway as
... walkway = 42w + 4w² = 2w(2w+21)
Using this formula, we can fill in the table

Answer:
In the function g(x) = 4x² + 1, <em>4</em> means that all the points in the parent function were multiplied by 4. <em>+ 1 </em>means that the parent graph will shift up by 1.
Answer:
This is linear equation you're asked to find C I guess so collect like terms and find X
x=-6-14
x=-20
C. Zero slope. If it's going straight up and down, there is no slope.
Answer:
this is my answer but it's on you if you think this answer is correct or wrong
