Domain is all the possible inputs of an equation. In this example, the only concern is the x + 5 because the denominator cannot equal 0 because we can't divided by 0. So we set x + 5 equal to zero and solve for x.
x + 5 = 0
x = -5
The restriction is that x cannot equal -5.

Answer:
x = 4.
Step-by-step explanation:
We see that it passes through the x axis at the point (4, 0) so x = 4 is a solution.
Check by solving the equation
x^2 - 4x + 13 = 13
Subtract 13 from both sides:
x^2 - 4x = 0
x(x - 4) = 0
x = 0 or x - 4 = 0, so:
x = 0 or 4.
93+36+m=180 combine like terms
93+36=129 rewrite
129+m=180 subtract 129 from both sides
180-129=51 rewrite
M=51 and to check this just plug 51 in for m
93+36+51=180
93+36=129
129+51=180
180=180
Hope this helps have a nice nite!
