Since <em>x</em> ² + 8<em>x</em> + 7 = (<em>x</em> + 7) (<em>x</em> + 1), we have for <em>x</em> ≠ -7,
<em>y</em> = (<em>x</em> + 7) / (<em>x</em> ² + 8<em>x</em> + 7) = 1/(<em>x</em> + 1)
so <em>y</em> is undefined at <em>x</em> = -1, indicating a vertical asymptote, and there is a hole/removable discontinuity at <em>x</em> = -7. Then the answer is D.
For this case we can use the following trigonometric relationship to solve the problem:

Where,
C.O: opposite leg
h: hypotenuse
Substituting values we have:

Clearing x we have:

Making the corresponding calculations we have:
Answer:
The value of x is given by:
10-x+y÷2
10-(5)+(2)÷2
10-5+2÷2
7÷2
3.5???
I'm pretty sure that's correct, I'm sorry if it's wrong though
Answer:
1,236
Step-by-step explanation:
The absolute value defines as being the positive of the number.
Absolute value of 47 - 47
Absolute value of (-56) - 56
47 + 56 = 103
103 * 12 = 1,236
Hope this helps!
