Step-by-step explanation:
Answer:
State A was the <u>12th</u> state to enter the Union. State B was the <u>11th</u> state to enter the Union.
Step-by-step explanation:
Let's call x to the order-of-entry of State B, therefore the order-of-entry of State A is x+1. Given that he product of their order-of-entry numbers is 132:
x*(x+1) = 132
x² + x - 132 = 0
Using quadratic formula:







The negative solution has no sense in the context of our problem, then the solution is x = 11.
3x+4=52
-4 -4
3x=48
divide by 3 on both sides
x=16
