Tell whether each triangle with the given side lengths is a right triangle: 5 feet 12 feet 15 ft

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
