Since there are 8 block on the left side and 3 on the right side, they have to have the same amount to be equal.

A) 8 = 3 + 3 → 8 = 6? No, this isn't right

B) 8 = 4 + 3 → 8 = 7? Nope

C) 8 - 3 = 3 → 5 = 3? No

D) 8 - 5 = 5 → 3 = 3? Yes, so to balance the two sides you would need to take 5 blocks from the left side (or add 5 to the right side but that isn't a choice)

Answer:

$2\sqrt{34}$

Step-by-step explanation:

We can add a line to create a triangle and a rectangle. The triangle will have side lengths 10 and 6. Furthermore, it will be a right triangle, meaning we can apply the Pythagorean Theorem to find x, the hypotenuse.

$6^2 + 10^2 = x^2\\x = \sqrt{6^2 + 10^2}\\ = \sqrt{136} \\= 2\sqrt34}$
