Simplify the rational expression(picture and choices attached)! 15 points and will give Brainliest. Due soon.

The answer should be:

The closest answer is A, so I'll go with that.

Step-by-step explanation:

So we have the rational expression:

First, remove the division sign. To do so, turn the division into multiplication and flip the second term:

Now, simplify. From the first term, in the numerator, factor out a x. On the second term, factor out a 2x in the numerator and a x in the denominator:

Multiply straight across:

Cancel out the (2x-7):

Cancel out the x:

At this point, we can factor the (4x^2-9) term, but we won't be able to cancel it out. Thus, this is the simplest it can get.

To get the answer, expand the numerator:

Thus, the answer is...

A?

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

a
