Answer:

x + 3

Step-by-step explanation:

A 'sum' means addition, 'a number' is represented by a variable, in this case, I chose 'x'.  I could have picked any variable I wanted.

The sum of three and a number means:  three plus some number, which is

 3 + x       in math language.     We write variables before constants, so it gets

                  rewritten as x + 3

inna [77]

Answer:

The area is 28\ m^{2}

Step-by-step explanation:

I assume that the figure is a square

The area of a square is equal to

A=b^{2}

where

b is the length side of the square

In this problem we have

b=2(\sqrt{7})=2\sqrt{7}\ m

substitute in the formula

A=(2\sqrt{7})^{2}

A=28\ m^{2}
