can someone please tell me if this answer is correct
p3+2p9=0
p+2p39=0
3p12=0+12=0
3p/3 = 12/3 p=4

Yes, it's correct.
You can prove it by substituting 4 for p in the original problem.

Ms Sue, Can you explain how you substitute the 4 for the p. I'm not sure if I have to add 2with the 4 or do I multiply 2 with the 4.
43+2( 4) 9 +0

math grade nine  Ms. Sue, Wednesday, April 13, 2011 at 4:46pm
Multiply 2 * 4. The expression 2p means 2 times p.
p3+2p9=0
4  3 + 8  9 = 0
12  12 = 0
