20x^3-14x (20)^3(x)^3-14•x look at it this way (20•20•20)(x•x•x)-14 (400•20)(x^2)-14 8000x^2-14 7986x^2 A factor of 7986 is 11 The lowest factor is 2 So the answer is 2x^2
You practically answered this one yourself by giving some of the equation we need already filled in. It would look like this: A(t)=500(1.04)^7. Start by taking 1.04 to the power of 7 to get A(t)=500(1.3159). Finish by multiplying to get A(t)=$657.97
