Answer:
x = 13
Step-by-step explanation:
In a triangle, all the angles equal 180 so
2x + 5x - 7 + 6x + 18 = 180
combine like terms
13x + 11 = 180
13x = 169
x = 13
The answer is f(x) = (x/4) - 3
4/4=1-3=-2

Which Numbers or do you need help on all of them
There is a method I use called the x method, I can’t show it to you but I will do my best to explain it
Basically, the factors of 5 and 7 must equal 36, so it’s kind of like cross multiplying
5 X 1
1 7
Five times seven equals 35
1 Times 1 equals 1
35 + 1 = 36
This is the answer:
(5x+1) (x+7)
