<em>here</em><em>,</em><em> </em><em>we</em><em> </em><em>have</em><em>;</em>

<em>=</em><em>4</em><em>x</em><em>^</em><em>2</em><em>-22x</em><em>+</em><em>3</em><em>0</em>

<em>=</em><em>4</em><em>x</em><em>^</em><em>2</em><em>-</em><em>(</em><em>1</em><em>0</em><em>+</em><em>1</em><em>2</em><em>)</em><em>x</em><em>+</em><em>3</em><em>0</em>

<em>=</em><em> </em><em>4</em><em>x</em><em>^</em><em>2</em><em>-10x-12x</em><em>+</em><em>3</em><em>0</em>

<em>now</em><em>,</em><em> </em><em>taking</em><em> </em><em>common</em><em>,</em>

<em>=</em><em>2</em><em>x</em><em>(</em><em>2</em><em>x-5</em><em>)</em><em> </em><em>-6</em><em>(</em><em>2</em><em>x-5</em><em>)</em>

<em>=</em><em> </em><em>2</em><em>(</em><em>x-</em><em>3</em><em>)</em><em>(</em><em>2</em><em>x-5</em><em>)</em><em>.</em>

Answer:

4x^2-22x+30

=2(2x^2 - 11x + 15)

=2(2x^2 -6x -5x +15)

= 2 { 2x(x-3) - 5(x-3) }

= 2 (x-3) (2x - 5)

I'm confused on how to find the length of this triangle.​
sertanlavr [38]

the formula for area=l*w

you know one side is 1.1w (w representing the unknown side) and the area is 3.3w squared. now you need to plug in the numbers you know into your formula which would look like this: 3.3w squared is equal to 1.1w times w. now you need to solve for w by multiplying 1.1w and w to get 1.1w squared. now you are going to divide 1.1 w squared on both sides which gives you w equals 3

Final answer: w=3
