3x²-33x-180=3(x²-11x-60)=3(x-15)(x+4)
the roots are when x-15=0, x=15 and when x+4=0, x=-4
d and h are the answers.

Answer: $4.34
Step-by-step explanation:
Mon: 0.6x100= 60 cents
Tue: 0.6x130= 78 cents
Wed: 0.6x145= 87 cents
Thurs: 0.6x138= 82.8 cents
Fri: 0.6x210= 126 cents
60+78+87+82.8+126= 433.8 cents
There are 100 cents in a dollar
4.33.8 cents, so 4.34 if you round up (if the last number is five or greater round up)
