An open circle means any number except the one in the circle. Here the number in the circle is 3. The arrows go to both sides. This means every number except 3. The answer is c. Which states that every number is included except 3. Basically meaning x is never equal to 3.

Answers

Answer with explanation:

1)

          7x^3+8

we first cube a number x i.e. x^3

and then multiply it by 7 and then finally add 8 to the resulting expression.

2)

       (7x+8)^3

We first multiply the number x by 7 and then add 8 to it and then cube the resulting expression.

3)

                (7x)^3+8

We first multiply x by 7 to get 7x and then cube the number and finally add 8 to it.

4)

               7(x+8)^3

We add 8 to  a number x to get x+8 and then cube it and finally multiply 7 to the resulting expression.

       

(7x)3+8 8 added to the cube of 7x

(7x+8)3 The cube of the sum of 7x and 8

7(x+8)3 7 times the cube of the sum of x and 8

7x3+8 8 added to 7 and x cubed
