A = lb

So,

14=4b\\\\b=\dfrac{14}{4}\\\\b=3.5\ cm

So, the length of the other side is equal to 3.5 cm.

Seventeen members of Tim's family are going to an amusement park during the week of their family reunion. Adult tickets cost $34
baherus [9]

Answer:

c.

Step-by-step explanation:

Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.

We have $34x + $31.5(17 - x) = $558.

$34x + $31.5(17 - x) = $558

$34x + $535.5 - $31.5x = $558

$2.5x = $22.5

x = 9

Hence the answer is c.
