The top one is 30. 8*2=16. 12*2=24 then add them together. which is 30. I don't know the last one.
(2x-5y)+(x+y)=(2x+x)+(-5y+y)=3x-4y.
therefore:
(2x-5y)+(x+y)=3x-4y

876 square feet need to be painted.
Step-by-step explanation:
There are four walls in each bedroom, since she can't paint floors or ceilings. So we calculate the number of square feet of wall there is in one bedroom
(12*8)+(12*8)+(10*8)+(10*8)-60=160+192-60=292
There are 3 bedrooms so
292*3=876
