No. The comma isn’t necessary; therefore , it should be removed from the sentence.
I am absolutely sure that he poetic foot and the length of line make up the meter of the poem. This option is the only proper one because metre is on of the basic rhythmic structure<span> of </span><span>lines in verse, so I bet it's obvious now. I do hope you will find it helpful : )</span>
That expression can be simplified by combining like terms.
Like terms are terms that have the same variable(s) and the same exponent(s).
The like terms are 7x and 9x.
You can combine like terms by adding the coefficients (the number in front of the exponent) together and then tacking on the variable at the end.
7x + 9x = 16x
Add 16x back to the term that can't be combined (-8y), and the simplified expression is 16x - 8y
