Answer:
130
Step-by-step explanation:
If you replace the value of c with 130, you can multiply 13 with 130 to get your answer.
13 x 130 = 1690
Or, you can multiply 13 with 13 and add the 0 onto the end. This makes the same answer. To add a zero onto the end of a number multiply it by ten.
169 x 10 = 1690
