-3(2/5x-2)=18
multiply -3 by 2/5 and my -2
-6/5x + 6 = 18
subtract 6 from each side
-6/5x = 12
divide by -6/5, multiply 12 by -5/6
x = -10
THE ANSWER WOULD BE 5.5
EXPLANATION: AB IS 2.5 and DC IS 8
2.5 - 8 = 5.5

Step-by-step explanation:
<u>Step 1: Define</u>
5(2x - 1) - 2(3x + 2)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 10x - 5 - 6x - 4
- Combine like terms (x): 4x - 5 - 4
- Combine like terms (Z): 4x - 9
<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
I believe the answer is B: 3 + 7 + (-10).
