Perform the following operations and prove closure. Show your work. x over x+3 + x+2 over x+5 x+4 over x^2+5x+6 • x+3 over x^2−16 2 over x^2−9 − 3x over x^2−5x+6 x+4 over x^2−5x+6 / x^2−16 over x+3 Compare and contrast division of integers to division of rational expressions.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
