Let f(x) =4x and g(x) =3x-5. find (g*)

 272

Step-by-step explanation:

f(x) = 4x         g(x) = 3x - 5

(g × f)(x) = (4x)(3x - 5)

             = 12x² - 20x

(g × f)(-4) = 12(-4)² - 20(-4)

               = 12(16) + 80

               = 192 + 80

              = 272

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
