If you are looking for √16, you are looking for the square root of 16. The square root of a number is defined by what number multiplied by itself will get you.
x^2 (a number squared) = 16.
√16 = x.
Let's try from numbers 1-5 for a square.
1x1 = 1
2x2 = 4
3x3 = 9
4x4 = 16
√16 = 4.
I hope this helps!

All 3 sides of an equilateral triangle are the same.
Set up an equation with two sides equaling each other and solve for n:
2n +15/4 = 7n
Subtract 2n from both sides:
15/4 = 5n
Divide both sides by 5:
n = (15/4) / 5
n = 3/4
Now you have a value for n, replace n and solve for the length:
7n = 7(3/4) = 21/4 = 5 1/4
Each side is 5 1/4
<em>x = 9</em>
<em>y = 0</em>
- Step-by-step explanation:
<em>y = -2x + 18 </em>
<em>4y - x + 9 = 0</em>
<em />
<em>4(-2x + 18) - x + 9 = 0</em>
<em>- 8x + 72 - x + 9 = 0</em>
<em>- 9x + 81 = 0</em>
<em>81 = 9x</em>
<em>x = 81 : 9</em>
<em>x = 9</em>
<em />
<em>y = - 2×9 + 18</em>
<em>y = - 18 + 18</em>
<em>y = 0</em>
Answer:
15% should be the answer because 60 + 25 is 85 and the remaining is classic rock which is 15%
