Answer:
Step-by-step explanation:
let x and y be length and width of rectangle.
Perimeter=2(x+y)
area=xy
2(x+y)=1/2 xy
4(x+y)=xy
4x+4y=xy
x y-4y=4 x
y(x-4)=4 x
![y=\frac{4x}{x-4}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4x%7D%7Bx-4%7D)
Answer: I think it is 47.23
Step-by-step explanation: Because 25% of 14.99 = 11.2425 But 35.99+11.2425 dose not seem right so I pretty sure it would be 35.99+11.24= 47.23

Hopefully this is right.... sorry if it is wrong
Answer:
What grade of math is that?
Step-by-step explanation:
If they were all the same number, then each one would be 1/3 of 57. That's 19. All three integers would be 19 ... an odd integer. All you have to do is take 2 away from one of them and glue it onto another one of them, and you'll have your three consecutive odd integers.
Answer: y=4
Step-by-step explanation:
We have a khown angle wich is 30 degree .
Cos 30 = root square of 3 /2
So root sqaure of 3/2 = 4 root square 3 / x
X= 4 r.sq 3 / r.sq 3/2 = 8
So we just need to apply the pythagorian theorem
X^2= y^2+ 48
64 = y^2 +48
Y^2 = 16
Y=4
