step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

answer: the actual answer is a. good bank will have the least amount in fees per year.

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
