Alright...so the coordinates of an ordered pair have opposite signs [one sign is positive while the other is negative] so we could have an example of (-x,+y) or (+x,-y) ...that means out of the 4 quadrants these points could be in the 2nd quadrant or the 4th quadrant or corners of the graph
Jason would has 66 coins in his piggy bank because 31+26+29=86-20=66 Hope I could help!!
(c+8)(c-8)
3(2y+5)(2y-5)
There are no like terms so it's still ab^2-b
The answer is 24.
8 + 8 + 4 + 4 = 24
