IRISSAK [1]

Answer:

<h2>x = - 1.14 or x = 2.64</h2>

Step-by-step explanation:

2x² - 3x - 6 = 0

Using the quadratic formula

x =  \frac{ - b± \sqrt{ {b}^{2}  - 4ac} }{2a}

a = 2 , b = - 3 , c = 6

Substituting the values into the above formula

We have

x =  \frac{ -  - 3± \sqrt{ { - 3}^{2}  - 4(2)( - 6)} }{2(2)}

x =  \frac{3± \sqrt{9 +48 } }{4}

x =  \frac{3± \sqrt{57} }{4}

x =  \frac{3 -  \sqrt{57} }{4}  \:  \:  \:  \: or \:  \:  \:  \:  \: x =  \frac{3 +  \sqrt{57} }{4}

We have the final answer as

<h3>x = - 1.14 or x = 2.64</h3>

Hope this helps you

Help with 6th grade math!

The perimeter of a rectangle is the sum of all its sides. As a formula, this is 
P = w + w + l + l = 2w + 2l = 2(w + l),
where P is perimeter, w is the width, and l is length.

Let's apply this formula to your question and substitute given information, then solve for l.
P = 2(w + l)
10x + 6 = 2(3x - 3 + l).
10x + 6 = 6x - 6 + 2l
4x +12 = 2l
l = 2x + 6
