Which of these is the algebraic expression for "seven more than the product of three and some number?" (3 points) 7 + 3 + x 3 + 10 ÷ x 3x + 7 3 + 7x I WILL GIVE BRAINLEST IF ANSWERED TODAY

answer:   14

step-by-step explanation:          

pu you stank bo u ugly bo lol

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
