In round 1, cathy chose 24. keiko scored 36 points. make a game board. mark cathy's choice and keiko's factors.

7

step-by-step explanation:

-4n -6 = -34

-4n = -28

divide both by -4

n = 7

proof

7*-4 = -28

-28 -6 = -34

answer:     true

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
