Write an equivalent expression by distributing the "-−" sign outside the parentheses: -(2.4f+g)-6

-2.4f - g -6

Step-by-step explanation:

Distribute the negative to +2.4f and +g

a negative * a positive equals a negative

so the +2.4f turns to a negative and the +g turns to a negative

The -6 is outside the parenthesis, so you do not distribute the negative sign to this.

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
