DS:
1)If \(n= p^2-p+17\), is \(n\) prime?

1)\(p\) is prime

2)\(p\) is an integer less than \(17\)

2)Is \(2|xy^2|> 0\)?

(1) \(x > 0\)

(2) \(xy > 0\)
is-2-xy-152250.html

3)Is \(|p|^2<|p|\) ?

1.\(p^2\leq{1}\)

2.\(p^2-1\neq{0}\)
is-p-2-p-151153.html

4)If \(y=\frac{|x+1|}{x}\) and \(x\neq{}0\), is \(xy>0\) ?

A)\(x^2+2x+1>0\)

B)\(y\neq{0}\)
if-y-x-1-x-and-x-0-is-xy-152900.html

PS:

I)2
