1. I think of a positive number, multiply it by 4, add six, and then divide the answer by
2, and square the result. Then I subtract 9, and divide the result by the number I first
thought of. My answer is 20. What number did I think of?

Respuesta :

Answer: 2

Step-by-step explanation:

2 times 4 = 8

8 plus 6 = 14

14 divided by 2 = 7

7 squared = 49

49 minus 9 = 40

40 divided by 2 = 20
