F(x)=x2-9x+8 f(x)=x2-16x+63
f(x)=x2-7x-18
f(x)=x2-5x-14
these ones I need help with all of them and the same format this is algebra

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?

Use the data on the dot plot to answer the question.how many people read for more than three hours last week? i'm on a unit test review

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]
