answer:

1. yes

2. no

3. yes

4. no

step-by-step explanation:

  • for 1, yes because no matter what they are the signs are still the same
  • for 2, no because the signs have changed — 2/5 is positive now
  • yes because even though there is addition now, the signs are the same. when you use kcc (keep change change), the sign changes to +
  • no, because the coefficient for p is changed, which won't be true or give us the same result
Yes, no, Yes, no just a simple answer
