Remember that polynomials are closed under addition, subtraction, and multiplication, but they are not closed under division. The only division you have there is B; therefore the correct answer is
B.
A.

. The result is still a polynomial; therefore, answer A is incorrect.
B. 
with a remainder of 26. The result is not a polynomial anymore; therefore,
B is the correct answer.
C.

. The result is still a polynomial; therefore, answer C is incorrect.
D.

. The result is still a polynomial; therefore, answer D is incorrect.
Answer:
112.5 square feet
Step-by-step explanation:
The scale model is 6 x 3 and the actual patio is 15 x W
By the definition of a scale model,
15/6 = W/3
15 = 2W multiply both sides by 6
15/2 = W divide both sides by 2
Area of the patio = length * width
Area = 15 feet * 15/2 feet = 225/2 square feet = 112.5 square feet
The answer to this question would be (0,0)
The answer for this equation full simplify is (D.)
From second equation y = 8 - x so
7x + 2(8 - x) = -14
5x = -14 - 16 = -30
x = -6
and y = 8 - -6 = 14
Answer x=-6,y=14
