Simplify the expression 5(x-3)(x^2+4x+1)
it would be I think answer number 3
Answer:
Verified
Step-by-step explanation:
Let the diagonal matrix D with size 2x2 be in the form of
![\left[\begin{array}{cc}a&0\\0&d\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Da%260%5C%5C0%26d%5Cend%7Barray%7D%5Cright%5D)
Then the determinant of matrix D would be
det(D) = a*d - 0*0 = ad
This is the product of the matrix's diagonal numbers
So the theorem is true for 2x2 matrices
807 divided by 7 = 115.2857143
Answer:
2,020
Step-by-step explanation:
671 X 3 = 2,013
2,013 + 7 = 2,020
