Answer: 52 degrees
Explanation:
For this problem, we must know that the complement of an angle is the measure of which will make a 90 degree sum.
So in this problem we simply solve the equation as follows:
38 + x = 90
x = 90 - 38
x = 52
Hence the complement of 38 is 52.

Answer: B. 
Step-by-step explanation:
1. By definition, the associative property of addition is:
2. Therefore, if you have the following expression:
You apply the Asociative property of addition by regrouping the numbers as following:
3. Then, you can conclude that the correct option is B.
discriminant= b^2-4ac= (-2)^2-4(4)(9)= -140<0
since discriminant <0, graph is always positive, x has no real roots
