Question

Combine like terms.

t+(t^2/2)+t^2+t

The expression 6s^2 represents the surface area of a cube with edges of lenth s. Find the surface area of a cube with each edge lenth.

Answer 1

t+(t^2/2)+t^2+t

3/2t^2 + 2t

Answer 2

you didnt even finish your second question...

Whatever the edge legth is. Square the lenght and then multiply by 6

Answer 3

2t + t^2/2+ 2/2(t^2)

2t + 3/2t^2

For second question, looks like you're missing an amount... "with each edge length ?"
