Alyssa swims 24 laps of freestyle and 75 laps of backstroke.
Write an equation to describe the
relationship between f, the number
of freestyle laps and b, the number
of backstroke laps.

answer: there are 453.592 grams in a pound.

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

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.
