(c-30)(c-120)=184\\
c^2-120c-30c+3600=184\\
c^2-150c+3416=0\\
c^2-150c+5625-2209=0\\
(c-75)^2=2209\\
c-75=\sqrt{2209} \vee c-75=-\sqrt{2209}\\
c=75+47 \vee c=75-47\\
c=122 \vee c=28

Express each ratio as a fraction in simplest form 16 feet out of 40 feet
Lady bird [3.3K]

Answer:

Step-by-step explanation:

Start by dividing top and bottom by 4

16 / 4 = 4

40/4 = 10

The result so far is 4/10

But 4/10 is not the answer. You can divide 4 and 10 by 2

4/2 = 2

10/2 = 5

Answer: 2/5
