Answer:</h2>
The expression which is equivalent to the following complex fraction is:

<h2>
Step-by-step explanation:</h2>
We are given a expression in terms of two variables x and y as follows:

Now, on taking least common multiple in the numerator as well as in the denominator we have:

which on further simplifying is:

You could use a simple pencil test to figure it out.
Place a pencil vertically on the paper, and move it left to right or vise-versa
When moving it make sure the pencil doesn't hit two points at once if it does it is not a function, but this is not the case
This is a function
60 miles because if you plug it in, it says she uses 2 gallons of gas. You can substitutes D=30(2), which comes out to 60
Answer:
A. P = 72 feet, A = 300 square feet
Step-by-step explanation:
✔️Perimeter = sum of all sides of the polygon = 15 + 16 + 17 + 8 + 16 = 72 ft
✔️Area of the polygon = area of a trapezoid = ½(a + b)h
Where,
a = 16 ft
b = 16 + 8 = 24 ft
h = 15 ft
Substitute
Area = ½(16 + 24)15
Area = ½(40)15
Area = 300 ft²

Solution:
~10 can go in to 25 two times.
10 + 10 = 20
25 - 20 = 5 (remainder)
~20 means that the whole number is 2.
2 5/10
~Simplify and Answer
2 1/2 or 2.5
