Answer:

a). 8(x + a)

b). 8(h + 2x)

Step-by-step explanation:

a). Given function is, f(x) = 8x²

    For x = a,

    f(a) = 8a²

    Now substitute these values in the expression,

    \frac{f(x)-f(a)}{x-a} = \frac{8x^2-8a^2}{x-a}

                  = \frac{8(x^2-a^2)}{(x-a)}

                  = \frac{8(x-a)(x+a)}{(x-a)}

                  = 8(x + a)

b). \frac{f(x+h)-f(x)}{h} = \frac{8(x+h)^2-8x^2}{h}

                      = \frac{8(x^2+h^2+2xh)-8x^2}{h}

                      = \frac{8x^2+8h^2+16xh-8x^2}{h}

                      = (8h + 16x)

                      = 8(h + 2x)

Dafna1 [17]

Answer:Scott is over 3 times older that Kate

Step-by-step explanation:

Kate is 3 years old. Her brother, Scott is 10 years old.

A) The ratio of Scott's age to Kate's age would be Scott's age divided by Kate's age. It becomes

10/3

B) To determine how many times older than Kate is Scott, we would express the ratio of their ages in decimal. Therefore

10/3 = 3.33

Therefore, Scott is over 3 times older that Kate
