Step-by-step explanation:
Given:
The equation is:
![(2x+1)(x-2)=0](https://tex.z-dn.net/?f=%282x%2B1%29%28x-2%29%3D0)
To find:
The values of a, b and b from the standard form.
Solution:
The standard form of a quadratic equation is:
....(i)
We have,
![(2x+1)(x-2)=0](https://tex.z-dn.net/?f=%282x%2B1%29%28x-2%29%3D0)
In can be rewritten as
![2x(x)+(2x)(-2)+(1)(x)+(1)(-2)=0](https://tex.z-dn.net/?f=2x%28x%29%2B%282x%29%28-2%29%2B%281%29%28x%29%2B%281%29%28-2%29%3D0)
![2x^2-4x+x-2=0](https://tex.z-dn.net/?f=2x%5E2-4x%2Bx-2%3D0)
...(ii)
On comparing (i) and (ii), we get
![a=2,b=-3,c=-2](https://tex.z-dn.net/?f=a%3D2%2Cb%3D-3%2Cc%3D-2)
Therefore, the correct option is C.
Answer:45 miles in one hour. You take the total of 315 and divide that by the 7 hours and that gives you how much is in the one hours

Answer: $23,600. ; $318,600
Step-by-step explanation:
From the question, we are informed that a house on the market was valued at $295,000 and after several years, the value increased by 8%.
The value of the increase will be 8% of $295,000. This can be mathematically written as:
= 8% of $295,000
= 8/100 × $295,000
= 0.08 × $295,000
= $23,600
The current value of the house will be:
= $295,000 + $23,600
= $318,600
Answer:
I believe the correct answer from the choices listed in the image is the second option. The statement that allows us to conclude that line m and line n are parallel would be that angle 2 and angle 7 are equal. They are alternate exterior angles. Hope this answers the question.
