I believe the answer would be 6:5 because you divide both 18 and 15 by 3.
The answer is (3x^2 - x +2 )= to AC
Area = 1/2 |BD| |AC|
(9x^3 - 3x^2 + 6x) = 1/2 (AC) 6x
3x ( 3x^2 - x +2 )= 1/2 (AC) 2(3x)
3^2 - x +2 = AC
469.1 yd^2 because I plugged it into the equation and I got that as the answer
2. $1000/65hrs = $15.38 per hour
3. Assuming that you get time and a half for OT.
$25 x 45hrs + 1.5(20hrs x $25)
= $1125 + $750
=$1875
4. You lose 8 hrs pay. So you only work 32 hrs.
32hrs x $25 = $800
