Answer:
l = 16, w = 8
Step-by-step explanation:
Let l = length
Let w = width
Area = w * l
128 = w * l
w = 128/l
Perimeter = 2w + 2l
48 = 2w + 2l
48 = 2(128/l) +2l
48 = 256/l +2l
Multiply everything by l
48l = 256 + 2l^2
l^2 + 128 = 24l
l^2 + 128 -24l = 0
(l-16)(l-8)= 0
L = 16
L = 8
If you try them out, and test it, l = 16 would work:
2(16) + 256/16 = 48
32 + 16 =48
16 * 128/16 = 128
16 * 8= 128
128 = 128
Since I'm not sure if you are in advanced math or not, I will do it simple with guess and check
Try w is
So to my calculations of copping the other guy it’s -1/-3
To find the number of terms in the arithmetic sequence, we need to use the formula
where
![a_{n}](https://tex.z-dn.net/?f=%20a_%7Bn%7D%20)
is the nth number,
![a_{1}](https://tex.z-dn.net/?f=%20a_%7B1%7D%20)
is the first number, n is the number of terms and d is the difference of the two consecutive numbers.
7373 = 1313 + (n - 1)(303)
7373 = 1313 + 303n - 303
7373 = 1010 + 303n
7373 - 1010 = 303n
6363 = 303n
6363 ÷ 303 = n
n = 21
Therefore, there are 21 terms in the arithmetic sequence given.
Well we want to find out how much more will it cost to rent a ski boat than a sailboat for four hours.
All we have to do is Multiply 73 by 4 for the sailboat which gives you $292
Now we do the same for the ski boat. $88 * 4 = $352
So we now have to find out how much more it will cost for a ski boat than a sail boat. All we do is subtract 352 by 292
352
