Evaluate using substitution ∫(2x^5+6x)^3(5x^4+3)dx where b=0 and a=-1
i got to here and then got stuck u=5x^4+3 du=x^5+3x+c ∫(2x^5+6x)^3 u 1/(x^5+3x+c) ∫(x^5+3x)^3 u

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?
