Answer:
52 cents
Step-by-step explanation:
0.88 times 4 is 3.52, which is buying 4 boxes separately which means you'd save 52 cents if you bought 4 at once
Answer:
Option C and D
Step-by-step explanation:
For a quadratic function having no x-intercepts the discriminant should be less than 0 .
![D=b^2-4ac](https://tex.z-dn.net/?f=D%3Db%5E2-4ac)
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.
![x=-b+-\frac{\sqrt{b^2-4ac} }{2a} \\\\x=-b+-\frac{\sqrt{D} }{2a}](https://tex.z-dn.net/?f=x%3D-b%2B-%5Cfrac%7B%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D%20%5C%5C%5C%5Cx%3D-b%2B-%5Cfrac%7B%5Csqrt%7BD%7D%20%7D%7B2a%7D)
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
