Find the domain of the rational expression: x-5/3x-6

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

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
