Answer:
A. The value of n can be any positive integer resulting in the same factor
Step-by-step explanation:
Given
--- the right expression
Required
Possible values of n
Expand
Factorize
Factor out
<em>From the expression above, we can see that the result has the same factor. This means that options (b), (d) and (e) are not possible</em>
<em></em>
The above also shows that n can take any positive value.
<em>Hence: (a) is correct</em>
Answer:
x = 559.31 m
Step-by-step explanation:
Given in the question,
horizontal distance from airplane to the coral reef = 3172 m
outer angle of depression = 10°
inner angle of depression = 90 - 10
= 80°
It is a question of right angle triangle, we will use trigonometry identity to solve the question
<h3>Tan(80) = base / height</h3>
Tan(80) = 3172 / x
x = 3172 / Tan(80)
x = 559.31 m
Answer:
Well in my view, I think it is -9 degree celsius.
(I am sorry if the answer is incorrect because I am just a high school freshmen and I love solving new problems) ;)))

Answer:
<h2>x² + 7x - 7</h2>
Step-by-step explanation:
f(x)=7x-3 and g(x)=x²-4
(f+g)(x) = f(x) + g(x) = 7x - 3 + x²- 4
= x² + 7x - 7
