What is the answer to this?

There are 6 faces on a cube. Each face is equal to the area of one square.

Area of one square = 2.5 x 2.5 = 6.25 units^2

Surface area = 6.25 x 6 = 37.5 units^2

Hope this helps!! :)

37.5

Step-by-step explanation:

Since it is a cube, all edges are 2.5. To find one side, you do 2.5x2.5. That gives you 6.25. And you have 6 sides. So 6.25x6 = 37.5.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

y > 1/3x

y < = -x + 4

hope this : )
