Answer:
c=
or c=3.46410161514
Step-by-step explanation:
Use Pythagoras theorem: a²=b²+c², where a is the side opposite the right angle, and b and c are the other sides:
a²=b²+c²
4²=2²+c²
16=4+c²
c²=12
c=
or c=3.46410161514
To simplify the expression stated, it is better to write it in the numerical form. The statement is:
<span>quantity 12 x plus 36 over quantity x squared minus 4 x minus 21
The numerical form is:
12x+36 / (x</span>²-4x-21)
Simplifying,
12x+36 / (x<span>²-4x-21)
</span>12 (x+3) / (x+3)(x-7)
We can cancel the x+3 term, leaving only:
12/(x-<span>7)</span>
D seems to have the possibility of having the largest range.
