Answer:
what kind of practice test?
Step-by-step explanation:
i dont understand but if you need help practicing i will help you.
All of the equations contain -4 in their range.
A) -4 = sqrt(x) - 5
1 = sqrt(x)
x = 1; valid
B) -4 = sqrt(x) + 5
-9 = sqrt(x)
x = 81; valid
C) -4 = sqrt(x + 5)
16 = x + 5
x = 11; valid
D) -4 = sqrt(x - 5)
16 = x - 5
x = 21
I believe the equations contain square instead of square root, in which case the answer would be A because no other could have a negative range.
Just look up 53 1/3 yards in feet. This would mean that the football field is 160 feet.
It's probably 2/6
Because comic books are 2 dollars and since he bought a sandwich it's 2/6 because the sandwich is 6 dallors
The answer is 81.
Hope i helped!
