So basically you just want to isolate the variable. So you want n on a side all by itself. so first you multiply by -2 to both sides, that will leave you with the equation n+4=18, then you subtract 4 from both sides, this will give you the equation n=14. To make sure this solution is correct, you can plug it back into the equation filling 14 in for n, this equation is 14+4/-2=-9, and this solution works. Hope this helped :)
You know we can't draw it, but I will give you all information so that to enable you draw this parabola
y = (x-4)² +3.
1-The coefficient of x =1 so it's positive, the parabola passe by a minimum or opens upward
2- It doesn't intercepts the x-axis since it has no zero value
3- its shifted 3 units upward & shifted 4 units to the right
4- its axis of symmetry is x=4 & its minimum is at (-3 , 3)
Hope this will help

Answer:
Step-by-step explanation:
By the Triangle Proportionality Theorem:
By cross-multiplication:
Distribute:
Subtract 12x from both sides:
Hence:
