3a2 + 2a + 2a2 is equal to

yanalaym [24]

Answer:

5a^2 +2a

Step-by-step explanation:

Like terms are ones with the same exponent of x. They can be combined.

3a^2 +2a +2a^2

= (3a^2 +2a^2) +2a

= (3+2)a^2 +2a

= 5a^2 +2a

A and B are n×n matrices. Check the true statements below: A. (detA)(detB)=detAB. B. The determinant of A is the product of the

Rudik [331]

Answer with Step-by-step explanation:

We are given that

A and B are matrix.

A.We know that for two square matrix A and B

Then, $det(AB)=det(A)\cdot det(B)$

Therefore, it is true.

B. det A is the product of diagonal entries in A.

It is not true for all matrix.It is true for upper triangular matrix.

Hence, it is false.

C. $\lambda+5=0$

$\lambda=-5$

When is a factor of the characteristics polynomial of A then -5 is an eigenvalue of A not 5.

Hence, it is false.

D.An elementary row operation on A does not change the determinant.

It is true because when an elementary operation applied then the value of matrix A does not change.
