Answer:61
Step-by-step explanation:
Its common logic
5x + 6 + (-7x - 4)
5x + 6 - 7x - 4
-2x + 2
K=10
Here is the equation
180-115=65
(4K+5)+(6k+10)+65=180
1) factor to see if you can get anything to cancel out before you multiply
2) the rest of my work is shown in the picture attached
3) the answer is n^2
