Step-by-step explanation:
Step 1: Define
b(x) = |x + 4|

Answer:
5/8
Step-by-step explanation:
3/8 + 1/4
To add these fractions, you need a lowest common denominator. Both 4 and 8 "go into" 8, so the lowest common denominator is 8.
In order to change the denominator 4 to 8, you need to multiply both the numerator and the denominator by 2. So, 1/4 becomes 2/8.
Now, the problem is 3/8 + 2/8.
You can add the numerators, because the denominator is the same for each fraction.
3/8 + 2/8 = 5/8
