Is positive. In fact, the square of any (real) number other than 0 is always positive.
2 n/3 would be the closest answer although it looks as if the 2 is supposed to be multiplied by n/3 which would lead me to write it as 2(n/3)

Answer:</h3>
19.5 inches
<h3>
Step-by-step explanation:</h3>
Let r represent the length of one of the sections of rope (in inches). Then the total length of the original rope is ...
... 8r +28.9 = 184.9
... 8r = 156 . . . . . . . . . . . . subtract 28.9; next, divide by 8
... 156/8 = r = 19.5
The length of each of the sections is 19.5 inches.
77%
I like to use ratios and cross multiply for problems like this. Take the part (1001) over the whole (1300), and that equals x percent of 100 percent.
1001/1300 = x/100
100100 = 1300x
x = 77
Answer:
In the model, you can see that it is split up into four parts. It also shows that the whole model is 2/3. So, an equation you could write is
