If a real car is 9 feet long and the hood is 3 feet long, how long would the hood of the car be in a 12-inch- long scale model of the car?

a - 2 inches
b - 4 inches
c - 3 inches
d - 6 inches

i dont knwo i rly need pounts plz

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

answer: the first graph
