Answer:
2x^2 - x - 15 = 0.
Step-by-step explanation:
In factor form this is
(x + 5/2)(x - 3) = 0
x^2 + 5/2x - 3x - 15/2 = 0
x^2 - 1/2x - 15/2 = 0
Multiply through by 2:
2x^2 - x - 15 = 0.
It can be anyways..400 minutes after 30 or 30 minutes after 400
Answer:
so its 50+.25(x) = y or 140. x is amount of minutes y is total
The answer is option d) T(Q+6.5) = R
