Rule-3 angles of a triangle =180 degrees . One angle is a right angle which is 90 degrees so the remaining 2 must equal 90 so the equation is so 90=(15x)+(8x-2) and now we just have to solve what is the value of x.
First we move -2 to the other side of the equation as +2 so we get 92=15x+8x next we put the 15x and 8x together and get 23 so 92=23 times x. So we divide 92 by 23 and the value of x is 4
-35

It will take them 16 days because 13 x 6 is 78 and we know there's 24 hours in a day so we have to do 52 x 24 and get 1248 then divide it by 78 and get 16 correct me if I'm wrong
Answer:
(x -3)(x + 6)
Step-by-step explanation:
x^2+ 3x – 18
As you know
- 18 = -3 * 6
3 = -3 + 6
So
x^2+ 3x – 18
= (x -3)(x + 6)
