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 value of x is 24.
<h3>What is Trigonometry?</h3>
Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
Given:
P= 12√2
angle =45
Using trigonometry
sin 45= P/H
1/√2 = 12√2/H
H= 12√2*√2
H= 12*2
H= 24
Hence, the value of x is 24.

If you dont follow the right steps in the right order or properly, you won't end up with the right answer:
For example 3 x 5 + 7
If you do multiplication then add you get 22 which is correct.... but!!
If you add then do multiplication you get 36 which isn't right
Remember always follow PEMDAS
P-Parenthesis
E-Exponents
M or D- Multiplication or division (go left to right)
A or S- Addition or Subtraction (go left to right)
Your answer is 9.05, Thank you for your time :)
Answer:
y=1/4x-1.5
Step-by-step explanation:
So, because the line is parallel, the slope is the same. Then, to get the y-int, you do b=y-mx with the point, so the equation is b=-1-(1/4)(2), then you multiply to get b=-1-(0.5), so your y-int is -1.5.
