P=-25/4
You can divide 25/4 and you will get 6.25 or 6 (1/4)
Call the length
and the width
We are told:
1. "<span>The length of a rectangle is 3 times its width." i.e.:
2. "</span><span>The rectangle’s width is 4 m." i.e.:
So, by substitution we have:
Then we can use our area formula:
</span>
Here we have an arithmetic sequence:
a 1 = 20, d = 2, n = 35
S n = n/2 * ( a 1 + a n )
a 35 = a 1 + 34 d = 20 + 34 * 2 = 20 + 68 = 88
S 35 = 35/2 * ( 20 + 88 ) = 35 / 2 * 108 = 1,890
Answer: In total, the theater seats 1,890 people
Answer:
From reading the question, it looks like you need 2 lines.
Try graphing (2, 5) and (-2, 3) for the first line, and (-2, 3) (-4, 0) for the second line. The answer should be correct.
I hope this helped!
