Answer:
OPTION C
Step-by-step explanation:
We have the following rules:
![$ \sqrt[a]{x} = x^{\frac{1}{a} $](https://tex.z-dn.net/?f=%24%20%5Csqrt%5Ba%5D%7Bx%7D%20%3D%20x%5E%7B%5Cfrac%7B1%7D%7Ba%7D%20%24)
and
OPTION A: ![$ x \sqrt[7]{x} $](https://tex.z-dn.net/?f=%24%20x%20%5Csqrt%5B7%5D%7Bx%7D%20%24)
= 
= 
So, it can be eliminated.
OPTION B: ![$ \bigg ( \frac{1}{\sqrt[7]{x}} \bigg )^9 $](https://tex.z-dn.net/?f=%24%20%5Cbigg%20%28%20%5Cfrac%7B1%7D%7B%5Csqrt%5B7%5D%7Bx%7D%7D%20%5Cbigg%20%29%5E9%20%24)
= 
= 
= 
So, this option is also eliminated.
OPTION C: ![$ x . \sqrt[7]{x} $](https://tex.z-dn.net/?f=%24%20x%20.%20%5Csqrt%5B7%5D%7Bx%7D%20%24)
= 
= 
= 
So, OPTION C is the answer.
Answer:
1. 322.01
Step-by-step explanation:
Formula: v=pi X r^2(h/3)
Answer:
no
Step-by-step explanation:
The 5x+30 is the supplementary angle of the interior one:
180 - 5x - 30 = -5x + 150
Then they have to add up to 180:
4x-9 + 2x+3 -5x + 150 = 180
which simplifies to x = 36
So the angles would be 135, 75 and -30, which is impossible!
Answer:
x=4
Step-by-step explanation:
-3(4x+3)
you need to break open the paranthesis
-3 times 4x equals to -12x. -3 times 3 equals to -9. That means that this expression is equal to -12x-9.
4(6x+1)
you need to break open the paranthesis
4 times 6x equals to 24x. 4 times 1 equals to 4. That means that this expression is equal to 24x+4.
-12x-9+24x+4=43
move all variables to the left side and numbers to the right side
-12x+24x=43-4+9
12x=48
x=4
Answer:
Step-by-step explanation:
- 4 + 4 = 0
- 9 + 8 = - 1
8 + (-1) = 7
-6 + (-2) = - 8
What is the sum of negative 9 and 7 = > - 9 + (-7) = - 9 - 7 = - 16
