(5x^3-7)(2x^2+1 answerrrrrrrrrr
The answer would be 5 hours and 50 minuets. It would be this because 2230 equals 10:30 count the hours between 1030 and 430 6 hrs then minus 10 min because the last hr isnt a full hour because it doesnt make it to 430.
0.0900-0.0088=0.0812
I did it by thinking of it as 900-88=812
Its the y=3x2one pretty sure
