You need to first make everything positive:
x^2=36
Then you need to get the square root of each side:
x=6 or -6
Hope this helps :)
Answer:
Month 5 the cost will be the same
Step-by-step explanation:
Make to equations from the given information
Let y be the cost, and let x be the number of months
Club A: y = 25x + 100
Club B: y = 20x + 200
It wants to know when the cost will be the same, so set the 2 equations equal to each other and solve..
25x + 100 = 20x + 200
5x = 100 (subtract 20x and 100 from both sides)
x = 20 (divide both sides by 5)
So after 5 months the cost will be equal,
I think it is 64 just multiply 4 times 4 times 4 because of the sides and to find volume you need to multiply the sides and the height so it should be 64.
