im confused on how to do this
Answers
Answer:
150
Step-by-step explanation:
Surface area is the area of all the surfaces (or sides). To find the surface area, find the area of one side of the cube. Since a side of a cube is a square, all the lengths are the same. So, 5*5= 25. There are 6 sides to a cube, so multiply 6 by one of the faces 's area (aka sides), so 6*25=150.

Answers
Answer:
(2.1, -1.3)
Step-by-step explanation:
Each line represents the set of points that satisfy the equation.
That means there's only one point that satisfies both equations (and thus, is the solution) - the point where they cross.
We can see it's a bit to the right of x=2 and a bit lower then y=-1, so the (2.1, -1.3) point looks like the most plausible estimate.
