Since we always want to have an a which equals 1 so then we don't have to do AC method, a longer process, we're going to want to take out the -1.
-1(x^2 - x - 42)
Then, we want to know what two number multiply to equal c (-42 here) and add up to equal b (-1 here). Those two numbers would be -7 and 6 since -7(6) = -42 and -7 + 6= -1.
So then from here we can just plop these numbers into (x+ __).
1(x-7)(x+6)
This is your final answer, A.
Answer:
3x + 10
Step-by-step explanation:
9 + x + 1 + 2x
Combine like terms
2x + x = 3x
Combine like terms
9 + 1 = 10
We’re left with 3x + 10
Your answer is 8x hope that helps
The answer should be C because if you use the rule , y2-y1/x2-x1 , you can find the slope which is equal to 5 so y=5x
I hope that helps you and really sorry if my answer was wrong but I tried my best!
