Answer:
x= - 4
Step-by-step explanation:
2 * x^2 + 8 * x = x^2 - 16
2 * x^2 - x^2 + 8 * x + 16 = 0
x^2 + 8 * x + 16 = 0
(x + 4) * (x + 4) = 0
x = - 4
We know that you have 83$ in your bank account.
Okay so what is 15+8=23 So that means you get 23$ per week.
Now what is 83+23=106
106+23=129
129+23=152
152+23=175
Now that was four 23's
That means it would take 4 weeks for you to have 175 dollars in your bank account.
Hope this helped.
