Answer:
5.5 inches
Step-by-step explanation:
1) the formula to find the area of a square is l^2= area and l=length
in this case we already know the area but not the length
so we have to find the square root of 30 as the opposite operation needs to be used to find the missing number
so
√30= 5.47
5.47 rounded= 5.5
the length of one side is 5.5 in
I believe the answer is C 1,300
Answer:

Therefore, at 9 pm the temperature was:
0 degrees - 4.2 degrees = - 4.2 degrees
