The expression 15n + 12n + 100 rersents the total cost in dollars for skis, boots and a lesson for n skiers. simplify the expression 15n + 12n +100, then find the total cost for 8 skiers.

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

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
