Answer: 

Step-by-step explanation:
Given :

re - writing the equation , we have

we need to find the value of a and b for which -2<x < 4 , this means that the roots of the quadratic equation are -2<x < 4.
The formula for finding the quadratic equation when the roots are known is :
- sum of roots(x) + product of root = 0
sum of roots = -2 + 4 = 2
product of roots = -2 x 4 = -8
substituting into the formula , we have:
, which could be written in inequality form as

comparing with
, it means that :


Answer: 1773.6 yards 5320.8 feet 64324.8 inches
Step-by-step explanation:
1 mile in yards = 1760 40.8 feet in yards = 13.6 1760 + 13.6 =<u> 1773.6 yards </u>
1 mile in feet = 5280 + 40.8 = <u> 5320.8 feet </u>
1 mile in inches = 63360
40.8 feet in inches = 964.8
63360 + 964.8 = <u>64324.8 inches </u>
