Answer:
2.05hrs
Step-by-step explanation:
Given he total cost c(x) of hiring a dump truck and an operator is described by the function c(x)=300+31x-3.90x^2 , where x is the number of hours worked. If c(x)=$220, then;
220 = 300+31x-3.90x^2
300+31x-3.90x^2 - 220 = 0
3.90x^2 + 31x - 80 = 0
x = -31±√31²-4(-80)(3.9)/2(3.9)
x = -31±√961+1.248/7.8
x = -31±47/7.8
x = -31+47/7.8
x = 16/7.8
x = 2.05
hence the number of working hours is 2.05hrs
624/3. 1. Divide 6 by 3
2. Divide 2 by 3 since it doesn't work bring down the 4 which gives you 24/3 and add a zero before you write the answer beacuse 2/3 wasn't possible
Your answer is
208
Formula for area of rectangle:
A= Length x width
Put values
A=(x-4)(5x+2)
Expand
A=5x²+2x-20x-8
Add like terms
A=5x²-18x-8
