The associative property could be that they are both even and they are both in the 3x table
you must factorize it as a difference of squares
a^2-b^2 = (a-b)(a+b),
9b^2-25 = (3b)^{2-(5)^2= (3b-5)(3b+5)
Answer:
59+j=a
Step-by-step explanation:
The equation i used says that 59 added to j is equal to a, I hope this helps you, sorry i couldn't explain it well enough :)
