Hi there! :)
Answer:

5n + 6 = -3n - 10
Solve for n:
Add 3n to both sides:
5n + 3n + 6 = -3n + 3n - 10
8n + 6 = -10
Subtract 6 from both sides:
8n + 6 - 6 = -10 - 6
8n = -16
Divide both sides by 8:
8n/8 = -16/8
n = -2.

Use the quadratic formula or complete the square by looking at the factors
Answer:
The actual length of the wall is 10.5 m
Step-by-step explanation:
Write and solve an equation of ratios to answer this question:
2 cm 3 m
--------- = ---------
7 cm L
Solve this for L by inverting both sides:
7cm L
---------- = --------
2 cm 3 m
and then multiplying both sides by 3m:
21
----- = L
2
The actual length of the wall is 10.5 m
