Adam writes 18y to simplify an expression with three like terms. what could the expression be?

Step-by-step explanation:

5y + 6y + 7y = 18yany numbers that add(or subtract) to equal 18, stick them before the y

or it could be : 10y + 10y - 2y = 18y or 5y + 10y + 3y or 30y - 20y + 8yI could go on forever...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
