What is the sum of r + s when r = –17.6 and s = 12.2? a. –29.8 b. –5.4 c. 5.4 d. 29.8

b

Step-by-step explanation:

in this case the negative is larger so it will still be a negative number

Option B = -5.4

Step-by-step explanation:

The sum of r + s when r = –17.6 and s = 12.2 is as:                                                                

r + s =

By putting values,  

r + s = ( -17.6 ) + ( 12.2 ),

r + s = -17.6 + 12.2,

r + s = -5.4

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
