Question

Which matrix is equal to... (picture added)

Answer 1

Its D on edge

Explanation:

Answer 2

D
`\left[\begin{array}{ccc}-6&-6.5&1.7\\-2&-8.5&19.3\end{array}\right]`

Explanation:

Two matrices are equal when they

• have the same sizes (so options A and B are false)
• have equal corresponding elements (so option C is false, because -6≠6, -6.5≠6.5, 1.7≠-1.7 and so on)

If in option D the second row is 2 -8.5 19.3 , then these matrix is equal to the given.
