Zidan is using the Rational Root Theorem to help find the roots of a 5th degree polynomial. He has discovered five roots and still has 4 to test. What is his next best step? 1. He should use the Factor Theorem to find the remaining polynomial roots.
2. He should test the remaining 4 roots.
3. He can stop testing because he has found all the roots.
4. He needs to pick one of the roots and use the quadratic formula to test it.

step-by-step explanation:

just add the numbers then put the negative sign on it

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.

for one thing their called fish not "fishes" and 2 fish can't be dead and alive and this question is absurd.
