Answer:
46
Step-by-step explanation:
x +3x+5x - 54 = 360
x +3x+5x = 360 + 54
9x = 414
x= 46
If solving for p, it is 239.98 bc when 284.97+194.99, 2p=479.96
Either one at any given time could be equal to zero. So
x + 2 = 0
x = - 2
x - 18 = 0
x = 18
I've enclosed a graph of this so you can see that the answers I've given are the ones expected.
Putting it in simpler terms
1.)11x^2-3x
2.)8x+1-x^2
3.)-x^2-x+8
4.)-2y+10-x^2
