Three is less than the sum of a number s and 4

Expression is,

Solution is -1 < s.

Step-by-step explanation:

Given phrase,

Three is less than the sum of a number s and 4,

∵ Sum of s and 4 = s + 4,

Now, in the inequality,

We use < for 'less than'

Hence, 3 is less than s + 4

Which is the required expression,

By solving it,

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
