Answer:
For problem 31: 25 counters in the 5th figure, 81 counters in the 9th figure, and 121 counters in the 11th figure.
Step-by-step explanation:
Since in the examples it shows 1 exponent 2, 2 exponent 2, and 3 exponent 2, that means all the rest will have 2 as an exponent. So the fifth figure would be 5 exponent 2, which is 5 times 5 = 25. The 9th figure would be 9 exponent 2, which is 9 times 9 = 81. The 11th figure would be 11 exponent 2, which is 11 times 11 = 121.
Is that all, or do you need answers for #'s 32, 33, and 34?

Answer:
n = m r - r t
Step-by-step explanation:
Solve for n:
m = n/r + t
Hint: | Reverse the equality in m = n/r + t in order to isolate n to the left hand side.
m = n/r + t is equivalent to n/r + t = m:
n/r + t = m
Hint: | Isolate terms with n to the left hand side.
Subtract t from both sides:
n/r = -t + m
Hint: | Solve for n.
Multiply both sides by r:
Answer: n = m r - r t
