Answer:
25 sheets of plywood will be needed
Step-by-step explanation:
Each sheet of plywood measures 
.
We have to cover the surface of the house, minus the surface of the hole of the stairs.
To know how many sheets will be needed, we divide the surface to be covered by the surface of each sheet
As we can't buy 0,75 of a sheet, we round it up, i.e. we will need 25 sheets of plywood for subflooring.

36p+4
Step-by-step explanation:
Answer:
t=-9
Step-by-step explanation:
2(2t-3)=6(t+2)
4t-6=6t+12
4t-6t=12+6
-2t=18
t=-9
Answer is 10(2k+5)
-----------------------------------
Work Shown:
20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)
Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer
Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
