Joe is training for a triathlon. She runs a distance of 2x miles, cycles a distance of (x2+7) miles, and swims a distance of (x-2) miles. Which simplified expression is eleventh to the total distance, in miles.

answer: a and b

step-by-step explanation:

$15 each

step-by-step explanation:

$45/3 children= $15 each

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
