Question

Your friends cheer and congratulate you as the lights flicker back on once you have closed the electrical circuit! You gaze around Scoops Ahoy and you discover that there is a piece of paper sticking out from under the counter. You lightly tug on the end of the piece of paper and a stack of folders falls to the floor. You kneel down and look closely at the manila folder. There is a strange sequence that reads "x^2+3x-4 and x=63 will gain you entrance." Solve the code!

Answer 1

4154

Explanation:

Given the expression:

`x^2+3x-4` and x=63

We simply substitute x=63 into the expression to obtain the code.

When x=63

`x^2+3x-4=63^2+3(63)-4\\=3969+189-4\\=4154`

The code is 4154.
