Example:
You owe someone $45.75 which is -45.75. You are able to pay that person the $45.75 which is positive and equivalent to the amount of money you owe. Add them together and you will get 0, meaning you don't owe them any money anymore.
Answer:
B
Step-by-step explanation:
Edge
a^2 + b^2 = c^2
In this case we're looking for C
so
(3)^2 + b^2 = (6)^2
9 + b^2 = 36
b^2 = 36-9
√b^2 = √27
b = 3√3
The answer is 36ft to the second power which is A.
