I’m pretty sure it’s 3 and a 2
Answer:
length = 14 m
width = 7 m
Step-by-step explanation:
l = length
w = width
l = 2w - 8
w(2w - 8) = 42
2w² - 8w - 42 = 0
you can factor out a 2 to work with smaller numbers:
w² - 4w - 21 = 0
(w - 7)(w + 3) = 0
w = 7
'w' cannot equal a negative so we discount it as an answer
find length:
l = 2(7) - 8
l = 14 - 8 or 6m
<u>By first equation,</u>
<u>Now, we can find the original value of y.</u>
<u>Now, we can find the original value of x.</u>
Therefore, the values of x and y are 5 and 2 respectively.
Answer:
6
Step-by-step explanation:
The period of a sinusoidal function in the form a * cos (b (x + h)) + m is 
. Therefore, we can see that "b" in g(x) is 1/3 and 1/3 substituted into is 2/1/3 which is 6.
Answer:
80 adults
Step-by-step explanation:
The number of kids is $10,000/$50 = 200. The number of adults is 2/5 of that, or 80.
