Answer:
3
Step-by-step explanation:
<em>This is cube root (hence the </em>![\sqrt[3]{}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%7D)
).
To find the cube root of a number, we are looking for a number that, when multiplied by itself 3 times, equals the number inside the sign.
So:
We know that 
, so this doesn't work.
We also know that 
, so this works.
Therefore the cube root of 27 is 3.
Hope this helped!
Answer: 
Step-by-step explanation:
Group like terms:
Simplify the arithmetic:
Add 7 to both sides:
Simplify the arithmetic:
Simplify the arithmetic:
Divide both sides by 3:
Simplify the fraction:
Find the greatest common factor of the numerator and denominator:
Factor out and cancel the greatest common factor and the answer will be:
The correct answer is D or the last choice. First, Pair up the values of both triangles in descending order then divide it. Having the equal answer will conclude that both triangles are similar.
A.(32/30) = (32/16) = (20/16)
1.067 = 2 = 1.25 = false
B. (110/8) = (80/6) = (60/5.5)
13.75 = 13.33 = 10.90 = false
C. (50/12.5) = (40/10) = (20/10)
4 = 4 = 2 = false
D. (60/30) = (30/15) = (30/15)
2 = 2 = 2 =True
