Take away 14 from both sides:

Multiply 4 on both sides :
Solve the system
<span>y = x + 4
y = 3x + 6
Note that both equations have been solved for y. Thus, you can set y = y, or
x+4=3x+6. Simplifying, -2 = 2x, or x = -1.
Another way to look at this would be x + 4 = 3x + 6.</span>
Answer:
18 sides
Step-by-step explanation:
A^2 + 31 = 155 - I squared each of b and c for those numbers
a^2 = 155 - 31
a^2 = 124
a = 4 * sqrt(31)
