Answer:

x=4.375

Step-by-step explanation:

-3(2x-7)+5=2x-9

-6x+21+5=2x-9

-6x+26=2x-9

-6x-2x+26=2x-2x-9

-8x+26=-9

-8x+26-26=-9-26

-8x=-35

-8x/-8=-35/-8

x=4.375

Answer: 35/8     or     4\frac{3}{8}

<u>Simplify each term</u>

<u></u>-3(2x)-3-7+5=2x-9<u></u>

<u></u>-6x-3-7+5=2x-9<u></u>

<u></u>-6x+21+5=2x-9<u></u>

<u></u>-6x+26=2x-9<u></u>

<u></u>

<u>Move all terms containing x to the left side of the equation</u>

<u></u>-6x+26-2x=-9<u></u>

<u></u>-8x+26=-9<u></u>

<u></u>

<u>Move all terms not containing x to the right side of the equation.</u>

<u></u>-8x=-9-26<u></u>

<u></u>-8x=-35<u></u>

<u></u>

<u>Divide each term by − 8 and simplify.</u>

<u></u>-8x/-8=-35/-8<u></u>

<u></u>

<u>Note</u>

Dividing 2 negative will give you a positive answer.

x=35/8

Find an expression for the area enclosed by quadrilateral ABCD below.
Helga [31]
  • ∆ABD is right angled hence area:-

\\ \sf\longmapsto \dfrac{1}{2}bh

\\ \sf\longmapsto \dfrac{1}{2}(4x)(3x)

\\ \sf\longmapsto \dfrac{1}{2}(12x^2)

\\ \sf\longmapsto 6x^2

There is only one option containing 6x^2 i.e Option D.

Hence without calculating further

Option D is correct

ratelena [41]

Answer:

Step-by-step explanation:

so let’s say x is the length.  Then the width will be 3x-4.  You add them together and multiply by two.  The perimeter is 72 so the equation equala 72.

Equation:

(x+3x-4)*2=72

(4x-4)*2=72

8x-8=72

8x=80

x=10

length:10

width:26
