3x - 4 = 18+5x
-3x -3x
-4-18 = 18 + 2x
-18
-22 = 2x
2x/2 = -22/2
x= -22/2
x= -11
Final answer: x = -11

Answer:
question 21 is x= 30
Step-by-step explanation:
when you multiply 7 by 5 you get 35 which is on the bottom side. So, to get x you multipy 6 and 5 and that equals 30.
<span> f(x) = x^2 + 4x − 1 and g(x) = 5x − 7
</span>(fg)(x) = (x^2 + 4x − 1)(5x − 7)
(fg)(x) = 5x^3 + 20x^2 - 5x - 7x^2 - 28x + 7
(fg)(x) = 5x^3 + 13x^2 - 33x + 7
answer is C. third choice
(fg)(x) = 5x^3 + 13x^2 - 33x + 7
