Answer: undefined in both cases.Explanation:1) Expression to evaluate:

2) You are asked to evaluate that expression for two different cases,
x = 0 and x = 3.3) First case:
x = 0The expression cannot be evaluated at x = 0, because the
denominators (both denominators)
equal 0, and the division by 0 is not defined.
So, the answer is
undefined.
4) Second case,
x = 3When you replace x = 3 you get:

Again, this result in a
division by 0, so you conclude that it is
undefined too.
The answer is 23 and 1÷9
First you multiply 4 by 5 and wind up with 20
Then you multiply four by 7÷9.
That gets you 28÷9
You take out all the nines you can from 28, three in this case.
That gets you 27÷9 + 1÷9
Your total thing is 20+27÷9+1÷9
That equals 20+3+1÷9
That equals 23 and 1÷9
It would be B because you would take amelias age and take two away since todd is five years younger to get the a-5.
hope this helps :)
