Answer: None of these answers are correct; tell this to your teacher. The 1st answer is closest to correct.
Step-by-step explanation:
The second and fourth answers are not viable because expanding them would result in x^3 which is not in the original equation.
1. 5x(x+3)-2(x+3)
5x^2+13x-6, This answer is closest to correct and may be correct in the case of a typo.
3. 5x(x-3)-2(x-3) ; Expand
5x^2-15x - 2x +6
5x^2-17x+6
Increases proportionally. (C)
the answer is
Y=2.5
X=3.75
Answer:
x =6t
y = - 5t
