Answer: N = 
Answer:
n = 20
Step-by-step explanation:
= 4
You need to get rid of the 6 in the denominator on the left hand side to make it easier to solve, so multiply both sides by 6. So you would get:
(
) × 6 = 4 × 6
n+4 = 24
Then just rearrange for n by subtracting 4 on both sides.
n+4 = 24
n= 24-4
n=20

Answer:
no solutions.
Step-by-step explanation:
8x + 14 -4x = 9+4x -5
8x-4x -4x = 9-5-14
0x = -10
anything multiplied by 0 is 0, so it's impossible to get -10 by multiplying by 0
The triangles are similar because the one on the left is just twice as big as the one on the right.
