Answer:
A. 9
Step-by-step explanation:
A counterexample shows that one side is true while the other is false
x>7 and x>11
sub in the answers
9>7 and 9>11 -this is true for the first half but false for the second
5>7 and 5>11 -this is false for both
13>7 and 13>11 -this is true for both
15>7 and 15>11 -this is true for both
Answer A is correct as it proves the statement to be incorrect
Calll x the smaller negative number.
The larger number will be x + 8
The product will be x(x+8) = 308
An the equation:
x^2 + 8x = 308
x^2 + 8x - 308 =0
If you solve that equation you will get x = -22 and x = 14.
The result that you are looking is the negative, x = -22.
The larger number is -22 + 8 = -14.
(-22)*(-14) = 308
Answer: x^2 + 8x - 308 =0
