Answer:
What is the total surface area of a cube with an edge on 4 1/2 feet... 121.5 feet
Step-by-step explanation:
Surface area = 6 × 4 1/2 × 4 1/2
Surface area = 121.5
A. 10
because 80 - 10 = 70 & 90 - 2(10) = 70
1. 2(4.5) + 0.5 = 9.5
2. 5(3) - 2 = 13
3. 2.5(18) + 0 = 45
Answer:
-18
Step-by-step explanation:
This is rather simple is it not?
To find the difference between the numbers, we simply have to subtract one from another.
, which can be simplified into
because subtracting a negative from a negative is simply done by adding the second negative as a positive to the first negative. Therfore
= -18 which is your answer.
-18 is how much each number is subtracted to get the next.
The answer is 13 ft because 39 times 4 is 156 and 156 divided by 13 is 12
