Answer 1

It is impossible and I'll tell u why

The choices are all odd numbers . Any four odd number equals an even number eg 3+3+5+89=100

but if you add another odd number to tht it will be an odd number but the answer is even

or maybe you had a type mistake cuz it's rare for test to have mistakes on them

Answer 2

3!+3!+3!+3!+3! = (6+6+6+6+6) = 30
