Umm, surface area of a cube = 6e^2 (six edge square) which is 6(3)sqaure = 54
Consecutive integers are 1 apart
they are
x,x+1,x+2
they have a sum of 51
x+x+1+x+2=51
3x+3=51
minus 3 both sides
3x=48
divide both sides by 3
x=16
16+1=17
16+2=18
the numbers are 16,17,18
C, both numbers form a mostly linear relationship.
We will use the distributive property, where
and
.



Therefore, the simplified expression is 4x+40.
