Answer:
A or C
Step by Step Explanation:
Answer:
Step-by-step explanation:
Two consecutive integers be x and (x+1)
x + x +1 = 7²
2x + 1 = 49
2x = 49 - 1
2x = 48
x = 48/2
x = 24
The consecutive integers are: 24,25
its A. because the exponent which in this case is 3, is multiplied 3 times. so 9 is multiplied 9 times
