The function d(x) =3x +2 determine how many donuts need to be purchased for a meeting, where x is the number of people at the meeting. the office manager uses h(d(x)) to find the amount of money to bring for the donuts purchase. the function h(x) = 2x + 7 . solve for how much money to bring when there are 8 people in the meeting.

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

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.
