The equations without a solution are A, B, and D since if you were to simply multiply out the equations with FOIL, you would receive X's that cancel out on both sides. I am not sure if you are looking for one solution but here's my input
Answer:
She can choose her electives in 20 ways.
Step-by-step explanation:
The order in which she chooses the courses is not important, which means that the combinations formula is used to solve this question.
Combinations formula:

How many ways can she choose her electives?
3 electives from a set of 6. So

She can choose her electives in 20 ways.
Answer:
36 m
Step-by-step explanation:
PT = x
This is True because of similar sides 
solve for x to get PT and you get 16
Then to find the perimeter you would do P = PR + PR + PT = 6m + 14m + 16m = 36m
Answer:
Option B.
Step-by-step explanation:
The given equation is
We need to find the property of equality to move the constant term to the right side of the equation.
In the given equation 6 is the constant term on the left side.
Using subtraction property of equality, subtract 6 from both sides.
So, the appropriate property of equality to move the constant term to the right side of the equation is Subtraction Property of Equality.
Therefore, the correct option is B.
