If the coordinate of vertex A is (-2.4), then the coordinate of vertex A' is

Hello!

The coordinate of vertex A' is (-2,-4)

Triangle A'B'C' is right underneath ABC.

If you have a look in the bottom left quadrant, you'll see that vertex A' is on a point. That point is sitting on -2. Simply put your finger on point A', and go up straight until you are on the x line. You'll find your coordinate. :)

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
