Answer:
1. x = -6, -8, -90
2. solutions for 
include -5, while -5 is not a solution for 
Step-by-step explanation:
19 yards divided by 2.5 minutes.
=19/2.5
= 7.6 yards/minute
Lets set the two numbers as 'a' and 'b'
Now let us set up some equations based on the information:
- sum of two numbers 49 --> a + b = 49
- difference of the two numbers is 15 --> a -b =15
Equations
a + b = 49 -- equation 1
a - b = 15 -- equation 2
Solve:
(equation 1) + (equation 2)
2a = 64
a = 32 -- equation 3
(equation 3)'s value of a into (equation 2)
32 - b = 15
b = 17
The products of 'a' and 'b' is 544
