The answer is A because all three of them have the same amount of coins
Answer:
The added values are 180.
Step-by-step explanation:
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
Answer:
15 meters
Step-by-step explanation:
One side is 2.5 meters, so if they're all the same then you would multiply that by 6
this is kinda easy and im gonna assume that the 4 is a exponent cuz f(2)=2(3)^4 then f=81
