15. The front of a storage bunker can be modeled by y = - (x - 72)(x + 72) where x and y
are measured in inches. The x-axis represents the ground. Find the width of the bunker at
ground level.
I
What is the width of the bunker at ground level?

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.  

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
