Let's assume
the range of the lengths of the skirts is t inch
now, we are given
to change hems either up or down 2 inches
so, total change in length should be 2
so, we will have right side =2
the length of the skirts is 20 inch
this will be either greater or lesser to length of skirts
so, the difference between them will be t-20
so, we get
(b)
now, we can find range
firstly, we will break absolute sign
for t<20
for t>20
because value of |t-20| must be positive
so, we get
Multiply both sides by -1
Add both sides by 20
Add both sides by 20
so, the range of the lengths of skirts is
18 in to 22 in..........Answer
(c)
Firstly, we will find difference in height of the model
5 feet 9 inches
6 feet =
now, we can find difference in height
and we are given
difference in length of skirts =2 in
so, the difference in height is greater than the difference in length of skirts
so, the answer is NO
