ABCD is a rectangle. Find the length of each diagonal. AC = 3(x - 5) and BD = x + 11
AC =
BD =
Please help!

AC=BD

3(x-5)=x+11

3x-15 = x+11

2x=26

x= 13

AC= 3(13 -5)= 24

BD= 13+11 = 24

Step-by-step explanation:

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
