Noah is getting balloons for his uncle's birthday party. he wants each balloon string to be 12 feet long. at the party store, string is sold by the yard. if noah wants to get 62 balloons, how many yards of string will he need?

  248

Step-by-step explanation:

A yard is 3 feet, so each 12-foot string is 4 yards long. The total length of string that Noah needs for his 62 balloons is ...

  (4 yards/balloon)×(62 balloons) = 248 yards

Noah needs 248 yards of string.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
