Cody was 165 cm tall on the first day of school this year, which was 10% taller than he was on the first day of school last year.

the solution is h=10 because you add 9 to each side of the equation.

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

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

i need a diagram

step-by-step explanation:
