Answer:
Option C and D
Step-by-step explanation:
For a quadratic function having no x-intercepts the discriminant should be less than 0 .
Now if this is less than zero if we plug in the values of a, b and c the square root of a negative number cannot be calculated thus giving us no real x-intercepts.
Here we can see that if we the value of D is less than zero the square would not be possible thus our correct choices are ,
Option C and D
For this, you would need to find 70% of 140. To do so you must do the following: 140 x 0.7, which would lead you to the following answer: 98. So, if someone were to weigh 140 pounds, they would have around 98 pounds of water in their body!
