Answer: OPTION A.
Step-by-step explanation:
Since the sum of the interior angles of a quadrilateral is 360 degrees.
We can write the following expression:
We know that ABEF≅CBED. Then:
Substituting and solving for , we get:
First, use the distributive property to expand the first equation.
3(x-4)=3*x+3*-4
=3x-12
Then we solve this as if it were an equation
3x-12≥5x+2
Minus 3x is
-12≥2x+2
Minus 2 is
-14≥2x
Which gets us that
(We had to flip the sign because we divided by a negative number).
You'll notice that this matches none of the choices, however, we are looking for the solution set, not the solution. In this case, it means any number that is less than 7. The correct answer is -10.

Answer:
9
Step-by-step explanation:
Hello There!
The image shown is a trapezoid
The dimensions of the non shaded area are:
Base 1 = 2 units
Base 2 = 4 units
Height = 3 units
Now that we have found the dimensions we want to solve for the area by using the area formula for a trapezoid
where a and b are bases and h is the height
knowing the dimensions all we have to do is plug in the values
so
so we can conclude that the area of the non shaded part is 9 square units
