First I did 8*6 which is 48 ( meaning there is 48 slices total)
Then take 36 and subtract that from 48 getting 12.
So there is 12 slices of pizza left over.
I believe it would be B. Because for one face of the cube you would need to calculate all four sides with however long the sides are.
S=sullivan's age
d=daughter's age
in 3 years time (s+3 and d+3)
sulivan is 3 times as old as daughter
s+3=3(d+3)
6 years ago (s-6 and d-6)
he was 6 times as old
s-6=6(d-6)
expand
s+3=3d+9
s-6=6d-36
for 2nd equation, add 6 to both sides
s=6d-30
sub 6d+30 for s in other equation
6d-30+3=3d+9
6d-27=3d+9
minus 3d both sides
3d-27=9
add 27 both sides
3d=36
divide both sides by 3
d=12
sub back
s=6d-30
s=6(12)-30
s=72-30
s=42
Mr. Sullivan is 42 now
Daughter is 12 now
Where else can see the picture
We gots 3 rectangles and 2 triangles
rectange area=length tiemsw dith
triangle=1/2 times base times h eight
rectangle left is
4 by 12 or 48 square inche
rectangle right is 9 by 4 or 36 squaer inches
back one is 15 by 4 or 60 square inches
triangles
there are 2 of them
12 by 9
2 times 1/2 times 12 times 9=108
add them all up
108+60+48+36=252 square inches
