Answer:
All real numbers except 3
Step-by-step explanation:
Given

Required
Determine the domain
We start by writing the following inequality

Add 6 to both sides


Divide both sides by 2



<em>As such, the domain of x is all real numbers except 3</em>
Answer:
46.5
Step-by-step explanation:
Of all straight angles have 180 degrees in them.
So, to find x we need to form this equation:
x + 65 + x - 22 = 180
2x + 43 = 180
2x = 180-43
2x = 137
68.5 degrees = x
68.5-22 = 46.5 degrees.
m<CBD = 46.5 degrees.
m<GBF = also 46.5 degrees because it is a vertical angle to <46.5 degrees.
181 is the only palindrome that has digits that when multiplied together give you 8.
Hope that helps :)
