Answer:

2\sqrt{5v}

Step-by-step explanation:

We can treat 20v as a regular number and not a term.

To simplify this square root, we need to break it down into parts which can be squared.

\sqrt{20v} = \sqrt{4\cdot5v}

Square root of 4 is 2, so that goes outside the radical.

2\sqrt{5v}.

Hope this helped!

Could someone help me complete this chart? It’s kinda confusing.
NARA [144]

Answer:

1. - completed

2. expanded = a · a · a · a

3. base = a | exponent = 5 | expanded = a · a · a · a · a

4. - completed

5. base = c | exponent = 3 | expanded = c · c · c

6. base = c | exponent = 4 | expanded = c · c · c · c

7. base = m | exponent = 2 | expanded = m · m

8. base = m | exponent = 3 | expanded = m · m · m

9. power = y⁵ | base = y | exponent = 5

10. power = y⁸ | expanded = y · y · y · y · y · y · y · y

hope this helps ! brainliest ?

Two cylinders are similar. The volume of the larger cylinder is 343 ft³ and the volume of the smaller cylinder is 125 ​​ft³. The
andreev551 [17]
Both cylinder are similar
Volume of a cylinder is πr^2h
if we consider both has same radius as they are similar
Lets say V1 is volume of small cylinder and V2 is volume of big cylinder.
V1/V2=πr^2x5/πr^2xh
125/343=5/h
0.36=5/h
h=5/0.36
h=13.72 ft

I need help on this thx ​

Answer: x = 75

Explanation: Basically, the three angles of the triangle add up to 180 degrees. The bottom left angle is ninety degrees. (You can figure that out by looking at the symbol that looks like a square in the bottom left angle of the triangle.) If you see that in other problems it means that that angle equals 90 degrees. To find the bottom right angle, you take 165 and subtract it from 180 because the diagonal line intersects the line that is going horizontally. That would give you 15. You can check this by adding 15 and 165 and you know that you’re right if you get 180. That gives you two angles. As I said in the beginning, the three angles of the triangle should add up to 180. Now you have 90 degrees and 15 degrees. You add those two and you get 105. Now all you have to do is subtract 105 from 180. You should get 75. You can check if you get the right answer by adding 90, 15, and 75 together. If you get 180 then you are correct. If you don’t get 180 then you did something wrong and should do the problem again. Sorry for the long paragraph, I wanted to get all the details in in case you had any questions. :) Hope this helps.
