Answer:

<h2>x = 2</h2>

Step-by-step explanation:

8(4-x)=7x+2\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\(8)(4)+(8)(-x)=7x+2\\\\32-8x=7x+2\qquad\text{subtract 32 from both sides}\\\\32-32-8x=7x+2-32\\\\-8x=7x-30\qquad\texy{subtract}\ 7x\ \text{from both sides}\\\\-8x-7x=7x-7x-30\\\\-15x=-30\qquad\text{divide both sides by (-15)}\\\\\dfrac{-15x}{-15}=\dfrac{-30}{-15}\\\\x=2

Answer:

x = 2

Step-by-step explanation:

Given

8(4 - x) = 7x + 2 ← distribute parenthesis on left side

32 - 8x = 7x + 2 ( subtract 7x from both sides )

32 - 15x = 2 ( subtract 32 from both sides )

- 15x = - 30 ( divide both sides by - 15 )

x = 2

Which of the following shows that polynomials are closed under subtraction when two polynomials, (5x2 3x 4) − (2x2 5x − 1), are
Verizon [17]

The closure property under subtraction is shown when the correct

result from the subtraction of polynomials is also a polynomial.

Response:

  • The option that shows that polynomials are closed under subtraction is; <u>3·x² - 2·x + 5 will be a polynomial</u>.

<h3>How is the option that shows the closure property found?</h3>

The closure property under subtraction for the polynomials is condition

in which the result of the difference between two polynomials is also a

polynomial.

The given polynomials being subtracted is presented as follows;

(5·x² + 3·x + 4) - (2·x² + 5·x - 1)

Which gives;

(5·x² + 3·x + 4) - (2·x² + 5·x - 1) = 3·x² - 2·x + 5

Given that the result of the subtraction, 3·x² - 2·x + 5, is also a

polynomial, we have, that the option that shows that polynomials are

closed under subtraction is; <u>3·x² - 2·x + 5 will (always) be a polynomial</u>.
