The bottom of a pylon is -3.5 yards below the ground. The top of the pylon is 2.5 yards above the ground. How tall is the pylon?

6 yards tall

Step-by-step explanation:

if we are looking at total length then 3.5 would be positive because even though it is under ground it still coaunts twrd total length.

  2.5 + 3.5 = 6

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
