Answer:
x= 2
x= -3
Step-by-step explanation:
<u>Solving as normal quadratic equation:</u>
- 2x^2+2x=12
- x^2 +x = 6
- x^2 + x - 6= 0
- x = (-1 ± √(1+4*1*6)/2
- x = ( - 1 ± √25)/2
- x = (-1 ± 5)/2
- x= 2
- x= -3
<u>Roots are</u> 2 and -3
Answer:
these are equal
Step-by-step explanation:
17/25 = 68 / 100 = 0.68
Answer:
The range is 95
Step-by-step explanation:
The range of a discrete data set is the difference between the least and the highest value.
The given date set is 83,70,21,48 and 116.
We sort it to get:
21,48,70,83,116
The range is 116-21=95
9514 1404 393
Answer:
The correct choice is marked
Step-by-step explanation:
When you end with a true statement, it means any variable value will make the equation true. There are infinite solutions.
When you end with a false statement, it means no value of the variable will make the equation true. There are no solutions.
