Notice that there are four terms in this expression, two of them contain the variable c (17c and -11c) and the other two have the variable d (4d and -6d).
The two terms that contain the variable c (17c and -11c) are said to be like-terms and these can be combined like this:

The other two terms (4d and -6d) are also like-terms and can be similarly combined:

So the end result is:

=
2) Translate to an algebraic expression:
The product of 11% and some number.
A product is the result of multiplying so you know that you will have to multiply two things.
11% can be expressed as a decimal: 11% = 0.11
"Some number" can be expressed as any letter you like, let's choose n, so...
(11%) X (n) = 0.11n
