Greetings from Brasil...
Here we have an indeterminacy 0/0
We can change variable or rationalize.......
Let's rationalize
{[√(X + 4) - 2]/X} · {[√(X + 4) + 2]/[√(X + 4) + 2]} = 1/[√(X + 4) + 2]
So, the limit will be 1/4

Answer:
4x² + 16x + 15 = 0
Step-by-step explanation:
We'll begin by determining the solutions to the graph.
The solutions to the graph is obtained by taking the values where the graph cut through the x–axis. This is illustrated below:
The solutions to the graph are:
x = –1.5 or –2.5
Finally, we shall determine the equation for the graph as follow:
x = –1.5 or x = –2.5
x = –3/2 or x = –5/2
Cross multiply
2x = –3 or 2x = –5
Rearrange
2x + 3 = 0 or 2x + 5 = 0
Combine
(2x + 3)(2x + 5) = 0
Expand
2x(2x + 5) + 3(2x + 5) = 0
4x² + 10x + 6x + 15 = 0
4x² + 16x + 15 = 0
Thus, the equation for the graph is:
4x² + 16x + 15 = 0
Answer:
5/12
Step-by-step explanation:
We multiply 3 by 3, and get 9.
Then we multiply 1 by 4, and get 4.
Next we give both terms new denominators -- 4 × 3 = 12.
So now our fractions look like this:
9
/12
−4
/12
Since our denominators match, we can subtract the numerators.
9 − 4 = 5
So the answer is 5/12
