Answer:
48 minutes.
Step-by-step explanation:
9 divided by 3 equals 3, 16 multiplied by 3 equals 48.
Number of cubes increases by 3 for each term.
an= 3n+1
Larger Number: L
Smaller Number: L-9
Larger Number + Smaller Number = 45
L + L - 9 = 45
2L = 54
L = 54/2
L = 27
Smaller Number = L - 9
27 - 9 = 18
Check. .. 27 + 18 = 45. CORRECT!
Larger Number is 27
Smaller Number is 18
Your answer is going to be letter B. the minimum point is in a negative spot so that cancels out A and D. the inside of the parabola is pointing up so that makes the answer B.
