to work these out divide the number by the denominator (bottom number) and multiply by the numerator (top number)
A principle square root of a real number that's not negative, such as 49,
is the square root of that number that is not negative.If you take the square root of 49, you get either -7 or 7, since both

and

equal 49. However, the principle square root would be
A) 7, since it's not negative.
The best interpretation of 2 in the given context is that; 2 represents the total length of fabric in yards purchased when no costumes were made.
<h3>Slope Intercept Form</h3>
We are given the relationship between the number of costumes that Kai made, x, and the total length of fabric that he purchased y, in yards as; y - 5x = 2
Where;
- x is number of costumes made
- y is total length of fabrics purchased.
Now, the general slope intercept form of an equation is given by; y = mx + c
Where c is the y-intercept which is the point where x is zero.
Thus, our equation can be rewritten as;
y = 5x + 2
Comparing with y = mx + c, we can say that c = 2
This means that at x = 0, y = 2.
In conclusion, the value 2 represents the length of yards purchased when no costumes were made.
