Fraction strips are rectangular pieces (electronic or copied on paper strips) to represent different parts of the same whole. They can be cut apart and manipulated to see how various parts can be added together to make the whole or compare different fractional amounts for equivalency
I see so many people ask this. What does this mean?
Answer: I will answer this but I need a bit more detail :)
Step-by-step explanation:
Part A:
The two factors of this expression are 9 and 7+2x. The first factor is a constant consisting of only one element. The second factor is a binomial which means it is consisted of two elements or terms.
Part B:
As already described above, the first factor only has 1 term and the second, being a binomial, has two terms.
Part C:
The term which is linked to the variable is 2x. This means that the numerical coefficient of the variable term is 2.
Moreover if we try to simplify the factors by distribution, we get,
63 + 18x
This will then tell us that the coefficient of the variable term is 18.
