The difference between the polynomials 5x² + 2x + 11 and 7 + 4x - 2x² is 7x² - 2x + 4 option (D)7x² - 2x + 4 is correct.
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
The complete question is:
FIND THE DIFFERENCE:
(5x² + 2x + 11) - (7 + 4x - 2x²)
We have two polynomials:
5x² + 2x + 11 and 7 + 4x - 2x²
We have subtract the polynomial 7 + 4x - 2x² from the polynomial 5x² + 2x + 11
= (5x² + 2x + 11) - (7 + 4x - 2x²)
Using distributive property:
= 5x² + 2x + 11 - 7 - 4x + 2x²
= 7x² - 2x + 4
The difference is 7x² - 2x + 4
Thus, the difference between the polynomials 5x² + 2x + 11 and 7 + 4x - 2x² is 7x² - 2x + 4 option (D)7x² - 2x + 4 is correct.

Standard form : Ax+By=C
Answer:
-x + 5y = 12
Step-by-step explanation:
Eliminate the fractional coefficient by multiplying both sides by 5:
5y - 15 = x - 3
Combine the constants: 5y = x + 12
Subtract x from both sides: -x + 5y = 12 This is in standard form

Answer:
Width of rectangular pen = 10 feet
Length of rectangular pen = 20 feet
Step-by-step explanation:
We are given the following in the question:
Area of rectangular dog pen = 300 square feet
Let be the width of the rectangular pen.
Then, length of the pen is given by:
Area of rectangular pen = Area of rectangle
Putting values, we get
Since, dimensions can never be negative, we get
Width of rectangular pen = 10 feet
Length of rectangular pen = 20 feet
