Raj made this argument: the triangle inequality theorem states that if the lengths of three sides of a triangle are a, b, and c, then a + b > c. for this reason, since a, b, and c are all positive numbers, the square of a + b must be greater than the square of c. however, for a right triangle, the pythagorean theorem states that if the lengths of the legs are a and b, and if the length of the hypotenuse is c, then a2 + b2 = c2, not a2 + b2 > c2. therefore, since the pythagorean theorem is known to be correct, and since right triangles should adhere to the triangle inequality theorem, the triangle inequality theorem must be incorrect. what is wrong with raj’s argument?

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
