The main denominator is 6
B because 6 years is 12(for months) times 6 which is 72 not 60
Answer: -56 or b.
Step-by-step explanation: -6+(-73)=-79 because the negative number means minus.
-79+(positive)56=-23 because a negative number plus a positive number is adding the positive number meaning you subtract but keep the negative sign
-23+(-33)=-56 because the negative number means minus
I don't know how to explain that is just kind of how it works.
But here's something for the future.
Positive+(Negative) is minus
Positive+Positive is plus (duh)
Negative plus negative is minus (or add but theres a negative sign)
Negative-negative=plus (idk why but its meth)
I believe what we are looking for is area. If so the formula for area of a rectangle is area equals width times length
A=wl
So:
9*13=117
The area would be 117, the amount of wall space needed is 117.
Hope this helps:)
