EXPLANATION
We want to simplify the rational expression

We can observe that the numerator of the given rational expression is a quadratic trinomial and the denominator is a difference of two squares
We need to split the middle term in the numerator and rewrite the denominator as a difference of two squares to obtain,

We now factor to obtain,

This implies that,

We now cancel out common factors to obtain,

The restriction is that, the denominator cannot be zero.
Thus

This implies that,
Answer:
The amount of change she received was
dollar.
Step-by-step explanation:
Price of each carton of milk is
cents and she bought 3 cartons of milk.
We know that, <u>1 dollar = 100 cents</u>

and
cents
dollar.
Thus, <u>the total price of 3 cartons of milk</u>
dollar.
She gave the cashier $10.
So, the amount of change she received
dollar.
A: ∠3 and ∠2
E: Since ∠3 and ∠2 lie on the same line and on a straight line, they must be supplementary as they must add up to 180° to satisfy the condition of a straight line.
