384 square inches

Step-by-step explanation:

The side is 10×5=50

There are 4 sides of equal surface area so we are at 200

The floor is 8×10=80 so we are at 280

The front is 8×5=40 and the back is the same so add another 40 so we are at 360

Add the little triangles which are 4×3=12 and you add the back as well so we get 384 square inches

System A: The lines overlap.

System B: The lines never intersect.

System C: The lines intersect at a point not on the y-axis.

System D: The lines intersect at the y-intercept.

Step-by-step explanation:

Got them right.
