​a) 28  ​b) 14
B.
​a) 14  ​b) 28
C.
​a) 40  ​b) 180
D.
​a) 6  ​b) 8

Answer 1

To evaluate the expression \( x + 10 \) for the given values of \( a(x) = 4 \) and \( b(x) = 18 \), we substitute each value into the expression.

1. For \( a(x) = 4 \):
\[
a(4) = 4 + 10 = 14
\]

2. For \( b(x) = 18 \):
\[
b(18) = 18 + 10 = 28
\]

Now, we compile the results:
- \( a) = 14 \)
- \( b) = 28 \)

Thus, the correct choice is **B**:
- **a) 14**
- **b) 28**
