Answer:C12=-3, C31=0, C22=0+5

Step-by-step explanation:

Matrix is the arrangement of elements in ROWS and COLUMNS

ROWS is the horizontal arrangement of elements.

Columns is the vertical arrangement of elements.

So in th matrix C

C12 means element of matrix C located at the point of intersection between first row and second column

C31 means element of matrix C located at the point of intersection between third row and first column

C22 means element of matrix C located ad the point of intersection between second row and second column.

28 in 21 in., 20 in.<br> Is this a right triangle?
ankoles [38]

Answer:

No, it is not a right triangle.

Step-by-step explanation:

The simplest way to determine is testing out the numbers with Pythagorian theorem.

If it complies with the theorem, it is a right triangle.

let's assume c = 28, b = 21, and a = 20

the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.

According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.

check:

c^2 = 28^2 = 784

a^2 + b^2 = 21^2 + 20^2 = 841

because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
