If (a=14q+9) and (b=14p+6), what is the remainder when (ab+a) is divided by 14?
Answer and explanation
Correct answer: 7
Step 1: The remainders of (a) and (b) are 9 and 6. Step 2: The remainder of (ab+a) comes from (9\times6+9=63), and (63=14\times4+7). Step 3: In a mixed expression, handle the remainder of each term separately.
