16) Which polynomial is in standard form?
A)
xy + xy2 + xy + 3
B)
xy + xy + xy + 3
C
xy5 + xy + xy2 + 3
D)
-xy² + xy - 2

Explanation:

The first term has its exponents add to 1+2 = 3

The second term has its exponents add to 1+1 = 2

The third term can be written as -2x^0y^0, and those exponents add to 0

The sums count down: 3, 2, 0

So standard form means we write the terms with the largest degree sums first, then second largest and so on.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

the answer is 13/48
