Last Question
Because this may not be the question you want, I'll omit the first step which should be done with latex. The key to all of these except C is to invert the second fraction (turn the second fraction upside down) and multiply.
A

=(6*-2) / (5*3) = - 12/15 = -4/5
B
= (7*5) / (4*3) = 35 / 12 = 2 11/12
C
Impossible to do 4/0 cannot be done.
D

= (-2*-4)/(3*5) =
8/15
The length of the third side is about 7.81 inches and the perimeter of the triangle is about 18.81 inches
We assume you mean

This is solved by writing 16 as a power of 4 and equating exponents.

2 = 3x - 7 . . . . . equate exponents
9 = 3x . . . . . add 7
3 = x . . . . . divide by 3
The solution is x = 3.
Answer:
The statement that correctly uses limits to determine the end behavior of f(x) is;
so the end behavior of the function is that as x → ±∞, f(x) → 0
Step-by-step explanation:
The given function is presented here as follows;

The limit of the function is presented as follows;

Dividing the terms by x², we have;

As 'x' tends to ±∞, we have;

However, we have that the end behavior of 7/x² as 'x' tends to ±∞ is 7/x² tends to 0;
Therefore, we have;

The statement that correctly uses limits to determine the end behavior of f(x) is therefor given as follows;
so the end behavior of the function is that as x → ±∞, f(x) → 0.
