Answer:
n = 3
Step-by-step explanation:
-6n - 20 = -2n + 4 (1-3n)
First distribute the 4 (1-3n)
-6n - 20 = -2n + 4 - 12n
Combine like terms on the right side
-6n - 20 = -14n + 4
Get 'n' on one side by adding -6n to both sides
-20 = -8n + 4
Subtract 4 to both sides
-24 = -8n
Divide -8 to both sides
3 = n
The answer would be the first phrase.
3x is 3 times x, and +4 is the sum of 3x and 4.
6 < c < 20,
Of course if you knew the triangle was a right triangle you could use the Pythagorean theorem to directly get the size of the third side.
