2(x -9) = 9 divided ( - 1/3) what value of x makes the equation true <br> plsss help :)))
Ivanshal [37]

Answer:

x = -9/2

Step-by-step explanation:

1. Divide 9 by -1/3:

\frac{9}{1} ÷ -\frac{1}{3} = \frac{9}{1} · -\frac{3}{1}

= -27

2. Divide both sides by 2:

2(x - 9) = -27

\frac{2(x-9)}{2} = \frac{-27}{2}

(x - 9) = -\frac{27}{2}

3. Add 9 to both sides:

x = -\frac{9}{2}

(or 4.5 if you need it in decimal form)

hope this helps!

PLEASE HELP AND SHOW ALL STEPS
Alja [10]

Combining the like terms, the simplified polynomials are given as follows:

a) 4x² - 14x + 17

b) -5x² - 20x + 8

<h3>How are polynomials simplified?</h3>

Polynomials are simplified combining the like terms, that is, adding these numbers with the same variable.

Item a:

4(x - 2)(x + 1) - 5(2x - 5)

Applying the distributive property:

4(x² - x - 2) - 10x + 25

4x² - 4x - 8 - 10x + 25

Combining the like terms:

4x² - 4x - 10x - 8 + 25

4x² - 14x + 17

Item b:

-5(x + 2)² + 28

-5(x² + 4x + 4) + 28

-5x² - 20x - 20 + 28

-5x² - 20x + 8
