You can take a square that sides have 4 cm each and know that you can times it by four. Or you can add 4 cm four times to get an answer. This shows that you can use multiple expressions to find an answer and that it is relatively easy. Ok to get your answer add x + 3/2x + 1/2x is 3x together.

I don't get it

What should I do?

Give me brainliest and thank me

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

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
