Answer:
99.33FT^2
Step-by-step explanation:
6x + 1 - 5x = 7 when x = 2
To check this answer, you simply need to plug in 2 for x in the original equation.
6x + 1 - 5x = 7
6(2) + 1 - 5(2) = 7
Simplify.
12 + 1 - 10 = 7
Simplify.
13 - 10 = 7
Simplify.
3 = 7
3 ≠ 7 Therefore x does NOT equal 2.

Answer: c ax + b = ax+ b
Step-by-step explanation: Seems like a trick question, especially since Answer c has no c in the equation. But once you put in numbers for a,b,and c, there cannot be infinite solutions for x in the first two examples.
Set up two or three equations and test them as proof.
8x²-18xy-5y²
8x²+2xy-20xy-5y²
2x(4x+y) -5y (4x+y)
= (2x-5y) (4x+y)
A. 12.2%
Steps:
1) 1380-1571= -191
2) -191/1571= -0.12
3) -0.12(100) = 12.15 = 12.2%
