Symmetry means that you should be able to draw a straight line and have both sides of the line be a reflection of the other (reflection like in a mirror or like if you put a miror at the middle of your face and someone looked in it they would see the other side)
so the answer is yes since it can be divided

Answer: Choice D. </h3>
Morgan forgot to distribute the negative sign to two of the terms in the second expression.
=============================================================
Explanation:
Focus on the numerators.
We have (3t^2-4t+1) as the first numerator and we subtract off (t^2+2t+2) as the second numerator.
Morgan needs to simplify (3t^2-4t+1)-(t^2+2t+2) for the numerator.
Mistakenly, she had these steps
(3t^2-4t+1)-(t^2+2t+2)
3t^2-4t+1-t^2+2t+2 .... her mistake made here
(3t^2-t^2)+(-4t+2t)+(1+2)
2t^2-2t+3
All of this applies to the numerator. The denominator stays at t+3 the entire time. So effectively we can ignore it on a temporary basis.
Here's what Morgan should have for her steps when simplifying the numerator.
(3t^2-4t+1)-(t^2+2t+2)
3t^2-4t+1-t^2-2t-2 ..... distribute the negative
(3t^2-t^2)+(-4t-2t)+(1-2)
2t^2-6t-1
Note in the second step, the negative outside flips the sign of each term in the second parenthesis.
Therefore,

which means 
Side notes:
- The fractions can only be subtracted since the denominators are the same.
- We have
to avoid a division by zero error. - Rational expressions are a fraction, or ratio, of two polynomials.
A) 324
I divided 240 by 20 to get how much it would cost per kg. For each KG the cost is $12. So then I multiplied 12 by what was asked of you (27) which lead me to the answer of 324.
B) 512
Same concept as A. Divide to get how much gasoline is used per mile. That was 4 miles per 1 gas. Multiply 4 by whatever you have been asked for (128). That leads you to 512.
C) 648
Same concept as above.
D) 5,445
