The question is:  What did he have in the beginning ?  All the information
we have happened after that.  So if we want to work through the information
towards the answer, maybe it makes sense to solve it starting from the end,
working backwards toward the beginning.

Manuel had  5  marbles left at the end of the story. 

Those  5  remained after he gave Matt  2 . 
Before he gave Matt  2, he had  7 .

Those  7  remained after he gave Matt half of his marbles.
Before he gave Matt half of his marbles, he had  14 .

Those  14  remained after he gave Lily  1  marble.
Before he gave Lily  1  marble, he had  15 .

Those  15  remained after he gave Lily half of his marbles.
Before he gave Lily half of his marbles, he had  <em>30</em> .

Find the degree of the polynomial<br> 2x^4y^2+9x^2y^5-3x^4y^4
coldgirl [10]

Answer:

the polynomial has degree 8

Step-by-step explanation:

Recall that the degree of a polynomial is given by the degree of its leading term (the term with largest degree). Recall as well that the degree of a term is the maximum number of variables that appear in it.

So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.

1) term  2\,x^4\,y^2  contains four variables "x" and two variables "y", so a total of six. Then its degree is: 6

2) term  9\,x^2\,y^5  contains two variables "x" and five variables "y", so a total of seven. Then its degree is: 7

3) term  -3\,x^4\,y^4  contains four variables "x" and four variables "y", so a total of eight. Then its degree is: 8

This last term is therefore the leading term of the polynomial (the term with largest degree) and the one that gives the degree to the entire polynomial.
