DEFG is a rectangle. DF = 3x – 3 and EG = x + 21. Find the value of x and the length of each diagonal.
antiseptic1488 [7]
Check the picture below.

bearing in mind that in a rectangle, both diagonals are the same length, therefore then,

\bf DF=EG\implies 3x-3=x+21\implies 2x=24
\\\\\\
x=\cfrac{24}{2}\implies x=12\\\\
-------------------------------\\\\
DF=3(12)-3\qquad \qquad \qquad \qquad EG=(12)+21

Drag the numbers to the boxes to order them from least to greatest value.
attashe74 [19]
Hello!

First you have to convert them all into numbers

2 = 2
47/14 = 3.35
sqrt of 5 = 2.23
0.9 = 0.9
0 = 0

Now you list them from least to greatest

The answer is 0, 0.9, 2,  \sqrt{5} ,  \frac{47}{14}

Hope this helps!
