I hope this helps:)
Answer:
B
Step-by-step explanation:
The closed circle at -
indicates that x can equal this value
The open circle at
indicates that x cannot equal this value.
All values of x between -
and
are valid, thus
-
≤ x <
→ B
Answer:
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Answer can be wrote in two ways. -2.5a-5/6b or -5a/2-5b/6
What you need to do is plot both lines. The point where they intersect is the solution.
