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>
Answer:
A
Step-by-step explanation:

Answer: 51
Step-by-step explanation:
Step 1: Replace x in y = 7x + 2 where x = 7.
y = 7(7) + 2.
Step 2: Solve the equation.
y = 49 + 2
y = 51
F(x)·g(x) = (3x-2)(5x) = 15x^2 -10x
