A) (f + g)(x) = f(x) + g(x) = (5x-12) + (11x+2) = 16x-10
B) (f × g)(x) = f(x)×g(x) = (5x-12)×(11x+2) = 5x(11x) -12(11x)+2(5x) -12(2) = 55x² -122x -24
C) f(g(x)) = 5(11x+2) -12 . . . . substitute g(x) for the x in f(x)
... = 55x +10 -12 = 55x -2
Answer:
F
Step-by-step explanation:
In scientific notation the answer is always going to be a whole number and a decimal point then another number then times 10
Ex: 8.27x10
.054x15=.81
7500+81%=7500(1.81)=$13575 after 15 years

Answer:
x² - 3x + 2
Step-by-step explanation:
Given
(x - 2)(x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 1) - 2(x - 1) ← distribute both parenthesis
= x² - x - 2x + 2 ← collect like terms
= x² - 3x + 2
x=4 because if you add 7 to 10 you get -2x-3=-14x then you add -2x to -14x and you get -3=-12 then you divide by -3 and -12 to get 4
