A boa constrictor is 18 inches long at birth and grows 8 inches per year. If the boa constrictor is 8 years old, how long is the boa constrictor?

• 46 inches
• 82 inches
• 64 inches

A boa constrictor is 18 inches long at birth and grows 8 inches per year. Write an equation to represent this situation

• y = 8x + 18
• y = 18x + 8
• 18x + 8y
• 8x + 18y

Given the following sequence, write a formula to determine the nth term.
12, 23, 34, 45, 56

• a_n = 5(n - 1) -56
• a_n = -5(n - 1) -12
• a_n = 11(n - 1) +12
• a_n = 11(n) + 12
