Answer:

The correct option is C.

Step-by-step explanation:

The given expression is the sum of two matrices.

[ –6 –2 2] + [–3 2 1]

Both are row matrices of order 1 × 3.

We can add two matrices if and only if order of both matrices is same.

In addition of two matrices, we need to add the corresponding elements of the matrices.

[ –6 –2 2] + [–3 2 1] = [ -6-3 -2+2 2+1 ]

[ –6 –2 2] + [–3 2 1] = [ -9 0 3 ]

The sum of given matrices is [ -9 0 3 ]. Therefore the correct option is C.

Please help I found this one a bit confusing

Brums [2.3K]

Answer:

7.2

Step-by-step explanation:

To reach point D from point C, you need to add 4 to the x-value of point C and take away 6 from the y-value. These numbers are the sides of the hypothetical triangle.

The Pythagorean Theorem states that $a^2+b^2=c^2$ . If we plug the side lengths in for a and b, we get $4^2 + 6^2 = c^2$ . This can be simplified to $16+36=c^2$ , or $52 = c^2$ . If we root both sides, we find that c is equal to $\sqrt{52}$ , which is slightly more than 7, at around 7.2.
