Answer:
Step-by-step explanation:
We have to organize the given polynomials from the least to greatest based on their degrees.
A). x + 2xyz
Here xyz = 
Power of x is = 1
Power of y = 1
and power of z = 1
So degree of (x + xyz) will be degree of the highest degree term = 1 + 1 + 1 = 3
B). 9x³y²
Degree of this term = power of x + power of y = 3 + 2 = 5
C). 18x²+ 5ab - 6y
Degree of the polynomial = Highest degree of the variable x = 2
D). 
Degree of highest degree term
= 4
So sequence of the polynomials based on their degrees will be
C - A - D - B [From lowest to highest]
Answer:
The greatest possible value of 3x - 2y is 20
Step-by-step explanation:
3x - 2y ------- 1
For getting the greatest possible value we must get the greatest value available, which is 10 and put it in place of x .
As 2y is being subtracted in the eq 1, we must put the smallest value available in the eq 1 to get the greatest possible result.
put x = 10 and y = 5 in eq 1
3(10) - 2(5)
= 30 - 10
= 20
Smallest possible value from the eqaution will be obtained by putting y = 10 and x = 5
3 (5) - 2 (10)
= 15 - 20
= -5
