Answer:
Option A.
Step-by-step explanation:
Consider the given problem is
Using the properties of radical expressions we get
![[\because \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%3D%5Cfrac%7B%5Csqrt%7Ba%7D%7D%7B%5Csqrt%7Bb%7D%7D%5D)
![[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7Bab%7D%3D%5Csqrt%7Ba%7D%5Csqrt%7Bb%7D%5D)
Taking out common factors.
The simplified form of given expression is 
Therefore, the correct option is A.
Answer:
79
Step-by-step explanation:
30 devided by 6 = 5
5+4 to the power of 3 + 10
4 to the power of three = 64
5+64+10
5+64=69
69+10=79
Factors of 9:
1x9
3x3
9x1
Did this even help like honestly lol
Answer:
D. 85
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180. Since we already know 2 of the interior angles of that triangle (40 and 55), we can subtract those two angles from 180 to find x.
180 - 40 - 55 = 85
For 45, 45, 90 angled triangles, the two legs are equal to 'x', and the hypotenuse is equal to
. Since we know the length of the hypotenuse, we can set this equal to it:
Divide the square root of 2 to both sides:
So the length of both AC and BC is approximately 5.657.
