You can put this solution on YOUR website!

+6.5+%3C=+p+%3C+7.5+
+4.5+%3C=+q+%3C+5.5+
i) Largest value of p+q: +p+%2B+q+%3C+13cm+ So p+q can reach up to, but not including, 13cm.
ii) Smallest value of p+q: +++p%2Bq++%3E=+11cm+ p+q can be as small as 11cm.
iii) Largest possible value of p-q: That will occur when p is maximum and q is minimum.
++++p-q++%3C+7.5-4.5+ —> +p-q+%3C+3++ —> p-q can be up to, but not including, 3cm.
iv) You can do the last one. You're only supposed to ask one question per post, and I've already answered three.
