Answer:
Option D is correct
Surface area of a cube is 294 square units
Step-by-step explanation:
Surface area of a cube is given by:
square unit
where
S is the surface area of a cube
a is the length of edge of a cube.
From the given figure, we have;
a = 7 units
then;
square units
Therefore, the Surface area of a cube is 294 square units
Answer:
The endpoint, B, is (-7, -8)
Step-by-step explanation:
When I get a problem like this, the first thing I like to do is find the difference between the midpoint and the starting point.
In this problem it would be -5 - -3 = -2 and -2 - 4 = -6.
(-2, -6) is what will help us find the endpoint.
Take the midpoint, (-5, -2), and add those coordinates to it.
-5 + -2 = -7
-2 + -6 = -8
So our endpoint is (-7, -8)
Here is a graph, to help you visualize it.
