meaning of (2, 20)?
O The rental cost for a dunk tanks starts at $20.
O The rental cost for a bounce house starts at $40.
O The costs for a dunk tank and bounce house are
the same for 20 hours.
O The costs for a dunk tank and bounce house are
the same for 2 hours.

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.

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
