There are many possible answers for this.
One example is below.
<em>S = the number of stations included when a person orders basic cable, write an expression for the number of stations a person has if he ordered basic cable and 7 premium channels.</em>
We can represent this as s + 7.
The value that we don't know is the number of
stations included when a person orders basic cable.
So we can represent that as s.
Then, since the person ordered 7 premium channels, that means he
is adding an additional 7 channels to his basic cable plan.
So we can represent this as s + 7.

Answer:
x = 4
Step-by-step explanation:
You want x when ...
g(x) = f(2)
2x -3 = 3(2) -1
2x = 8 . . . . . . . . add 3, simplify
x = 4 . . . . . . . . . divide by 2
Use pythagoras to find the 3rd length of the triangle:
Square root of 8.5^2-7^2= 4.82 yd
Find the area of the trapezium:
((2+(2+4.82))x7)/2
= 30.87 yd^2
To find the area of the parallelogram you just take away the area of the triangle from the area of the trapezium:
Area of triangle is (4.82x7)/2= 16.87yd^2
