If T is the midpoint of SV, ST= x + 4, and TV= 2x - 8, how long is SV?

The answer to your question is SV = 32

Step-by-step explanation:

Data

T = mid point

ST = x + 4

TV = 2x - 8

SV = ?

Process

1.- If T is the mid point of SV, that means that the distance from ST to SV is the same.

                    ST = TV

2.- Substitution

               x + 4 = 2x - 8

-Solve for x

              x - 2x = -8 - 4

-Simplifying

                   -x = -12

-Result

                    x = 12

3.- Find the length of SV

                  SV = ST + TV

                  SV = x + 4 + 2x - 8

                  SV = 12 + 4 + 2(12) - 8

                  SV = 16 + 24 - 8

                  SV = 40 - 8

                  SV = 32                          

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
