I have no idea how to do this. The homework is done in 20 minutes help

−4<x≤4

Step-by-step explanation:

Let's solve your inequality step-by-step.

−3<x+1≤5

−3+−1<x+1+−1≤5+−1(Add -1 to all parts)

−4<x≤4

−4<x≤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
