This would be a 4/5 ratio
7.2 because anything to the 0 power is 1.
That would be (y - 9)(y +9). When two binomials are multiplied, the distributive property is applied. However, if the equation is <span>y(3)(-3)y(3)(3), you just simply multiply them altogether. That would be -81y^2, which is not equivalent with y^2 - 81.</span>

3000 divided by 7 equals 428.5714285714, rounded equals 428.57.
