Explanation

Let's solve for x:

6 + 5x = 30 - x

Add x to both sides:

6 + 6x = 30

Subtract 6 from both sides:

6x = 24

Divide both sides by 6:

x = 24/6

x = 4

So, the correct answer is 4.

Explanation

To find the value of x^2, we need to square the value of x:

x^2 = (2)^2

= 2 × 2

= 4

So, the correct answer is: 4
