The dog eats 6 cupcakes in 22 days.
<em>(don't know why a dog would be eating cupcakes in the first place, but sometimes math questions don't make the most sense)</em>
The like terms are 16x and 2x
The numerator and denominator must be polynomials so
the answer to your question is - 7x / x^2 ( the last one on the right)
Number name is the same as word form
8.542 = eight and five hundred fourty-two thousandths.
hope this helps
