7 - 2x = 7 - 2(-4) = 7 + 8 = 15

<h3>Answer: 15</h3>

<u>Answer:</u>

  • The length of the side is 33 yards.

<u>Step-by-step explanation:</u>

<em>We can solve for 'b' using Pythagoras theorem. Let's solve it.</em>

  • 65² = b² + 56²
  • => 4225 = b² + 3136
  • => b² = 1089
  • => b = 33

Hence, the length of the side is 33 yards.
