from straight line
(x+12) + 100 + x = 180
2x + 112 = 180
2x = 180 – 112 = 68
x = 34
It would be 4x^2+11x-3
Or the far bottom right corner

Ida needs to hire a singer for her wedding.
For Singer A
Singer A is offering his services for an initial $65 in addition to $13.15 per hour.
65 + 13.15x
Singer B
Singer B is offering her services for an initial $73 in addition to $11.35 per hour.
73 + 11.35x
We equate both singers together
Singer A = Singer B
65 + 13.15x = 73 + 11.35x
We collect like terms
13.15x - 11.35x = 73 - 65
1.8x = 8
x = 8/1.8
x = 4.4444444444 hours
Approximately = 4.4 hours
The two singers will charge the same amount of money after 4.4 hours
