4 cups per quarter
4 x 7 = 28
28 kids can have a cup of hot chocolate.
Convert 1.5 and 0.8 from meters to millimeters,
1500*800,
A=120,000
I'd use synthetic div. here, with 2 as my divisor:
________________
2 / 1 -11 18
2 -18
----------------------------
1 -9 0
Note that the coefficients of the missing factor are given here and are 1 and -9. Thus, (x-9) is the missing factor.
