Number 8
the perimeter of rectangle = the perimeter of hexagon
2l + 2w = the sum of the sides on hexagon

Input what are given from the image
2l + 2w = the sum of the sides on hexagon
2(2x + 5) + 2(x) = 2x - 6 + 0.5x + 1.5x + 3x + 1 + 2.5x + 1.5x

Simplify the left side and the right side
4x + 10 + 2x = 11x - 5
6x + 10 = 11x - 5
<em>This is the equation</em>

Number 9
Solve the equation
6x + 10 = 11x - 5
6x - 11x = -5 - 10
-5x = -15
x = -15/-5
x = 3

The solution is x = 3

Need help please, does any one know how to do this​
ziro4ka [17]

Answer:

  • (6-u)/(2+u)
  • 8/(u+2) -1
  • -u/(u+2) +6/(u+2)

Step-by-step explanation:

There are a few ways you can write the equivalent of this.

1) Distribute the minus sign. The starting numerator is -(u-6). After you distribute the minus sign, you get -u+6. You can leave it like that, so that your equivalent form is ...

  (-u+6)/(u+2)

Or, you can rearrange the terms so the leading coefficient is positive:

  (6 -u)/(u +2)

__

2) You can perform the division and express the result as a quotient and a remainder. Once again, you can choose to make the leading coefficient positive or not.

  -(u -6)/(u +2) = (-(u +2)-8)/(u +2) = -(u+2)/(u+2) +8/(u+2) = -1 + 8/(u+2)

or

  8/(u+2) -1

Of course, anywhere along the chain of equal signs the expressions are equivalent.

__

3) You can separate the numerator terms, expressing each over the denominator:

(-u +6)/(u+2) = -u/(u+2) +6/(u+2)

__

4) You can also multiply numerator and denominator by some constant, say 3:

  -(3u -18)/(3u +6)

You could do the same thing with a variable, as long as you restrict the variable to be non-zero. Or, you could use a non-zero expression, such as 1+x^2:

  (1+x^2)(6 -u)/((1+x^2)(u+2))
