Angle B= 45 degrees
Angle A = 45 degrees
A and B are congruent since they are alternate exterior angles
5x-15 = 2x +21
5x = 2x +36
3x=36
X=12
B)
2x12+21 = 45
A)
5x12-15 =45

Answer: -15 and 2</h3>
You find this through trial and error.
A much more efficient way is to solve x^2-13x-30 = 0 using the quadratic formula. You'll find the two solutions to be x = 15 and x = -2
Going from those solutions, we get x-15 = 0 and x+2 = 0 which then turn into (x-15)(x+2) = 0 through the zero product property.
Hello :
<span>A) it is an even function because for all x in R :
f(-x) = 2(-x)²+1
= 2x²+1
f(-x) = f(x)</span>
The tax rate in Maine is 5%, so add the number together and multiply the number by 0.05. The answer I got is 12.165
