To solve the expression \(2.98 \times 10 + 9.14 \times 10\), we follow these steps:

1. Distribute the common factor \(10\):
   \[
   10 \times (2.98 + 9.14)
   \]

2. Add the numbers inside the parentheses:
   \[
   2.98 + 9.14 = 12.12
   \]

3. Multiply by the common factor \(10\):
   \[
   10 \times 12.12 = 121.2
   \]

So, \(2.98 \times 10 + 9.14 \times 10 = 121.2\).
