Gary is 3 years older than twice the age of his sister, elena

an equation for this situation is:

B) G = 2E + 3

Step-by-step explanation:

The first thing we must do for this case is to define variables.

We have then:

G: Gary's age

E: Elena's age

We then have the following expression:

Gary is 3 years older than twice the age of his sister (Elena):

Using the defined variables, we can write the expression as:

G = 2E + 3

You are lucky I had this question before because your answer is incomplete. Hope I helped!

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
