Answer:
42
Step-by-step explanation:
To determine a + a² just substitute the value of a.
Given a = 6.
Therefore, a + a² would become 6 + 6² = 6 + 36
= 42
∴ a + a² = 42
For 6: 12, 18, 24, 30, 36
For 9: 18, 27, 36, 45, 54
For 7: 14, 21, 28, 35, 42
Easy! First just subtract it like you would! Then, when you get to the 4 tens of the number, explain how you subtracted that!
