Step-by-step explanation:
4x979
=>3916
3x+9-2<20
3x+7-25<25-25
3x-18=0
x=18/3
x=6
Standing pieces:
2(9x6)+4(9x3) = 108+108 = 216
“L” horizontal pieces:
cut it to 3 squares of 3x3 each
2x3(3x3) = 54
total surface area = 216+54 = 270cm^2
First, add all of the minutes together. You would get 75 minutes of practice per day.
Then you multiply 75 by 7, and you get 525 minutes.
He practices 525 minutes (or 8.75) hours per week
