Answer:
The roots of equations are as m = 
And n = 
Step-by-step explanation:
The given quadratic equation is 2 x² + 6 x - 1 = 0
This equation is in form of a x² + b x + c = 0
Let the roots of the equation are ( m , n )
Now , sum of roots = 
And products of roots = 
So, m + n = 
= - 3
And m × n = 
Or, (m - n)² = (m + n)² - 4mn
Or, (m - n)² = (-3)² - 4 ()
Or, (m - n)² = 9 + 2 = 11
I.e m - n = 
Again m + n = - 3 And m - n =
Solving this two equation
(m + n) + ( m - n) = - 3 +
I.e 2 m = - 3 +
Or, m =
Similarly n =
Hence the roots of equations are as m = And n = Answer
The values are |-3.25| = 3.25 and |-4.25| = 4.25
<h3>How to determine the values of the expressions?</h3>
The expressions are given as
|-3.25| and |-4.25|
The above expressions are absolute value expressions
And as a general rule, an absolute value expression, when evaluated must follow the following rule
|±a| = a
Using the above as a guide, we have
|-3.25| = 3.25
Also, we have
|-4.25| = 4.25
Hence, the values of the expressions are |-3.25| = 3.25 and |-4.25| = 4.25

Answer:
Step-by-step explanation:
Area of a rectangle is length times width. Since a rectangle has four sides, there will be two sides that have the length size and two with the width. Anyway, now we need to find what numbers multiply together to make 35.
7 and 5 are the only whole numbers that multiply together to make 35, so those hve to be the length and width. So two sides opposite each other are going to be 7 cm and the other two are going to be 5 cm
