Answer: 8x-12

Step-by-step explanation:

Remove these () from the first pair

9x-8-(x+4)

Subtract 9x from x - X is always one unless they give you a certain number for x to be. Also remove the remainder parenthesis from the second pair of numbers.

9x-x = 8x

Add 8 to 4

8+4 = 12

Answer is 8x-12

I hope that I explained it more to the point where you understand it

1. Amanda tells you that because a variable is in the denominator, the equation three over x plus one over three equals five ove
Hunter-Best [27]

Answer: x = 6

<u>Step-by-step explanation:</u>

\dfrac{3}{x}+\dfrac{1}{3}=\dfrac{5}{6}

(6x)\dfrac{3}{x}+(6x)\dfrac{1}{3}=(6x)\dfrac{5}{6}  <em>multiplied by common denominator</em>

18 + 2x = 5x

<u>       -2x</u>   <u>-2x</u>

18         = 3x

<u>÷3         </u>  <u>÷3 </u>

6          =  x

Since "x" is in the denominator, the restriction is that x ≠ 0.  If the solution was x = 0, then the solution would not be valid and would be eliminated as an answer.

Remember that "x" is just an unknown value.  It is possible to add two fractions together and have their sum be a fraction.

For example: \dfrac{1}{5} + \dfrac{2}{5} = \dfrac{3}{5} could be written as \dfrac{1}{5} + \dfrac{2}{x} = \dfrac{3}{5}.  When we solve it, we will get x = 5.

Answer: Edward

<u>Step-by-step explanation:</u>

f(x)=\dfrac{(x-1)(x+2)(x+4)}{(x+1)(x-2)(x-4)}

The denominator cannot equal zero, so:

  • x + 1 ≠ 0  → x ≠ -1
  • x - 2 ≠ 0 → x ≠ 2
  • x - 4 ≠ 0 → x ≠ 4

Those x-values are the asymptotes, which is where the function is undefined.

Help plz don't get this
loris [4]
(I see that your concentrating on the task at hand with those YT and fortnite tabs open)

The area of the parallelogram is "base times height," so its 20*8 which is 160.

To find the area of the triangle, we have to find the base which incorporates Pythagorean'd theorem.
100 - 64 = 36, sqrt 36 is 6. So the base of the triangle is 6, the height is 12.6, thus the area is 6.3 * 6, which is 37.8

Adding the two values up, we get 37.8 + 160 = 197.8
