Which expression is a simplified form of 22 – 2 + 15 + 3x2 – 3 – 5?

42-5=37

Step-by-step explanation:

uh I'm not sure I'm only in middle school lol. But I just did the math and then showed you the last step because I'm lame. LOL

8121 because

130,000 divided by 16 is 8121

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
