Answer:
Use F.O.I.L method First, Outter, Inner, Last
So:
5x*7x= 35x^2
5x*-6= -30x
7x*2= 14x2*-6= -12
So just add it all up, combine like terms and you have your answer.
35x^2 -16x -12
12x - 4
Step-by-step explanation:
Add like terms.
5x + 7x = 12x
2 + (-6) = -4
Therefore, (5x + 2) + (7x - 6) = 12x - 4.
Using the slope formula:
-0.03571428571
The Answer Is E, $6.75
