Mutiply the bracket by -2
(-2)(2y)=-4y
(-2)(-3)= 6
4y^3-4y+6+y
4y^3-4y+y+6 ( combine like terms)
4y^ 3-3y+6
Answer: 4y^ 3-3y+6
Answer:
Ok
Step-by-step explanation:
Answer:
B. $8
Step-by-step explanation:
Given:
Total payment, T = $160
Hourly rates = $t/hour
= total payment/total time worked
The question said, "worked 12 more hours than the amount she is paid per hour".
Total time worked = (12 + t) hour
Therefore, Hourly rates of payment, t = 160/(12 + t)
t^2 + 12t - 160 = 0
Solving the above quadratic equation,
t = -20 and 8
t = $8
