Add 4 from both sides. and the answer is X>7
Answer:
Step-by-step explanation:
a=3, b=-15, c=20
Discriminant can be calculated as
The roots are imaginary
The solution is
The roots are not real i.e these are imaginary
a=3, b=5, c=-8
Discriminant can be calculated as
The roots are real
By quadratic formula method
The solution is
which are required roots.
I choose this method because I can get the solutions directly by substituting the values in formula, and I don't have to guess the possible solutions.
You can do
3 * 2 and 11 * 2 which would be 6:22 and is still equal to the ratio 3:11. Your explanation can be the when divided by 2 or the number you multiplied by, you would get the original ratio
Examples:
6:22
9:33
12:44
<h3><em><u>$21.07 is the answer</u></em></h3>
<h3>Divide $84.28 by 4, you will get 21.07 which will be the answer....I hope this helped you</h3>
Answer:
Angle 1: 95 degrees
Angle 2: 85 degrees
Angle 3: 95 degrees
Step-by-step explanation:
Vertical angles are opposite and equal so in this case angle 1 and 3 are vertical and so are 2 and 85°
So that means angle 2 also equals 85 degrees and because of supplementary angles the other angle must add up to equal 180 degrees
85 + ? = 180
?=95
So both angle 1 and 3 equal 95 degrees
