The length would be:

80=2x
x=40, so the length is 40 yards.
Answer:
Step-by-step explanation:
121b^4 - 49 is a "difference of squares."
Formula for factoring a "difference of squares:"
a² - b² = (a - b)(a + b)
So: rewrite your 121b4 - 49 as 11²b^4 - 7² = (11b²)² - 7²
= (11b² - 7)(11b² + 7)
This answer matches the last of the four given answer choices.
