Answer: Choice A</h3>
Explanation:
The square root undoes the squaring operation.
Think of a square that is 1 ft by 1 ft. Its area would be 1*1 = 1 sq ft.
Now imagine you told your friend "the area is 1 sq ft" and you didn't relay the side lengths. Your friend would use the square root to find the side length is 1 ft.
I'm not sure why your teacher is using plus minus notation when that is not correct. Saying 
is not true. The result of a square root is simply one value only. If your teacher meant 
, then it would be a true statement; however, there's no need to involve negative numbers for this problem.
Answer: first problem 3rd choice The graph shifts vertically up 5 units
11.) the y intercept is -5
19.) f(-8) = -18
last item third choice All real numbers such that are ≥ 0 and ≤ 40
Step-by-step explanation:
19.) f(x)=2(-8 -3) + 4
2 (-11) + 4
-22 + 4
f(-8) = -18

Answer:
24
Step-by-step explanation:
Corresponding lengths are proportional. The ratio of the full length to the given part is ...
(30 +x)/30 = 45/25
1 +x/30 = 1 +4/5 . . . perform the division
x/30 = 4/5 . . . . . . . . subtract 1
x = 30(4/5) = 24
The missing side length is 24.
