What number goes on top

One positive number is 9 more than twice another. if their product is 95, find the numbers

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!
