R^2+2r-33=0 move constant to other side by adding 33 to both sides
r^2+2r=33 halve the linear coefficient, square it and add to both sides, in this case it is just one
r^2+2r+1=34 now the left side is a perfect square...
(r+1)^2=34 take the square root of both sides...
r+1=34^(1/2) subtract 1 from both sides
r=-1+34^(1/2) and -1-34^(1/2)
Answer:
11.400 dollars... is the answer
Answer:
$150 = 4 hours,
So, in a ratio, 4 : 150
=> 150 * 4.5 : 4 * 4.5
=> 675 : 18 hours
Therefore to earn $675 at the rate of $150 for 4 hours, Fatima will need to work for 18 hours to earn $675
