10x+6y=24, 15x+9y=36. If you multiply both sides by a number (2,3 etc) you get an equation that would have infinitely many solutions because they’re the same equation. Hope this could help you!! Gamer time

Answer:
B. 6
Step-by-step explanation:
the median is the middle of the set of numbers so the median of crunchy pb is 51 and the median of creamy is 45 so the difference between them is 51-45= 6

Answer:
(A+B)(A+B)=A.A+B.A+A.B+B.B
Step-by-step explanation:
Given that matrices A and B are nxn matrices
We need to find (A+B)(A+B)
For understanding the multiplication of matrices let'take A is mxn and B is pxq matrices,we can multiple only when n=p,so our Ab matrices will be mxq.
We know that that in matrices AB is not equal to BA.
Now find
(A+B)(A+B)=A.A+B.A+A.B+B.B
So from we can say that (A+B)(A+B) is not equal to A.A+2B.A+B.B because AB is not equal to BA in matrices.
So (A+B)(A+B)=A.A+B.A+A.B+B.B
