Test: ACT Math

1.

The lengths of the three sides of a right triangle form a set of consecutive even integers when arranged from least to greatest. If the second largest side has a length of x, then which of the following equations could be used to solve for x?

(x + 2)2 + (x – 2)2 = x2

x 2 + (x + 2)2 = (x + 4)2

(x – 1)2 + x2 = (x + 1)2

(x – 2) + x = (x + 2)

(x – 2)2 + x2 = (x + 2)2
