Answer:
The solution set represented by the following graph is:
{x | x∈ R, x < -2}
Step-by-step explanation:
Clearly from the figure we could see that the solution set is to the left of ' -2' and excluding the point '-2' since there is a open circle at -2.
This means that -2 is not included in the set.
Also in interval; form the set of points that belong to the solution set are:
(-∞,-2)
in set-builder form it is written as:
{x | x∈ R, x < -2}
Surface area= 24 ft^2
A cube has 6 faces, so the surface area of 1 face would be 24/6, which is 4 ft^2.
The formula for the area of a square is l x w, but in a square both are equal so you're essentially squaring one side.
Therefore, the area of a square ( 4 ft^2 ) can be square-rooted in order to find the length of an edge.
= 2
Therefore, the length of 1 edge of the cube is 2 ft

Well, since there is no image I am unable to say the exact volume. But here is the volume formula-
V=L times W times H
*V=volume W=width H=height
and you don't actually have to write times you can do the symbol.
Example- if I had a rectangular prism of the width being 5 cubes, the length 8 cubes, and the height 7 cubes(following how many gallons are in a cube 7.5) I would the use my formula. V=LWH- 8 times 7= 56 56 times 5=280 280 times 7.5= 2100
V=2100 (that is your answer reply If you didn't mean the volume or you don't get it)
Take the inverse of cotangent to get your degree measure, then plug it into each answer choice.
I am joyous to assist you anytime.
