the scale factor is 2.
because
if you look at the length <em>AL</em><em> </em>in the smaller shape, it is 2 squares.
now if you look at the length <em>AL</em><em> </em>in the enlarged shape, it is 4 squares.
to find the scale factor, do 4 ÷ 2 which is 2.
therefore the scale factor is 2
<em>We can also graph inequalities on the number line. The following graph represents the inequality x≤2 . The dark line represents all the numbers that satisfy x≤2 . If we pick any number on the dark line and plug it in for x, the inequality will be true.</em>
The value of x is 23.
Simply find the scale factor or what was used to dilate △MAH to produce △WCF.
Use the equation copy over the original,

Reduce,

So our scale factor is ¼ or 0.25
So if we use it and multiply the corresponding side of the missing side with the original we get,

Therefore 23 is our missing side! !
