The degree is 3.
This video explains it pretty well: https://virtualnerd.com/pre-algebra/polynomials-nonlinear-functions/polynomials/monomial-polynomial-degrees/polynomial-degree-definition
It's different because they have 2 different numbers<span />
Answer:
552
Step-by-step explanation:
This is a problem of permutation which can be solved by rule of fundamental counting principle.
This principle states that if there "m" ways of doing one thing and "n" ways of doing other. Then no. of ways in which both the things can be done together is "m*n". This can be extended for m, n, p,r, s things and so on.
example: if there are 5 shirts and 3 trousers then number of ways in which the shirts and trousers can be worn is 5*3 = 15 ways.
_____________________________________________
The given problem is on similar concepts.
here 6 short stories, 4 novels, and 23 poems have to be assigned to his class.
Thus it can be done in 6*4*23 = 552 ways.
B. because on a square everything is equal

Find area of the border :
--------------------------------------------------------
Area of the room = 22 x 25 = 550 ft²
Area of the rug = 238 ft²
Area of the border = 550 - 238 = 312 ft²
--------------------------------------------------------
Define y:
--------------------------------------------------------
Let the width be y.
--------------------------------------------------------
Find area of the border in term of y :
--------------------------------------------------------
The area of the border = 22y x 2 + 25y x 2 - 4y² = 94y - 4y²
*We need to take away 4y² because the 4 corners will be overlap twice if we don't.
--------------------------------------------------------
Solve y :
--------------------------------------------------------
94y - 4y² = 312
4y² - 94y + 312 = 0
2y² - 47y + 156 = 0
<span>(y - 4)(2y - 39) = 0
</span>y = 4 or y = 19.5
--------------------------------------------------------
Answer: The border can be 4 ft or 19.5 ft
