No, because the 9 pounds would cost 22.5, and that is 5 cents more than he has
Step-by-step explanation:
-14x²-1≠0
x²≠ -1/14
Option C
36 x 3/9.
3/9 = 0.33
0.33 x 36 = 12
The expression is undefined when C, x = 9.
The way that this expression can be undefined is if the denominator is 0 (dividing by 0 is undefined). To make the denominator 0, that means that 9 - x =0. That means that x = 9. So, when x = 9, the denominator is zero, meaning that the expression is undefined when C, x = 9.
