#10x+5# is of order 1 and has two terms

7 lots of #x# plus 3 lots of #x# is a total count of 10 lots of #x#

Write as:#" " 10x+5#

Consider the following example

#a " "#is the same as #a^1# and is of order 1
#axxa" "#is the same as #a^2# and is of order 2
#axxaxxa" "#is the same as #a^3# and is of order 3

So

#10x+5# is of order 1 and has two terms
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Just to make it really clear
If your expression hade been #10x^2+5# then it would have been of order 2
