Answer:

100,100

Step-by-step explanation:

perimeter=400 m

length=x

let width=y

2(x+y)=400

x+y=200

y=200-x

area A=xy=x(200-x)=200x-x²

$\frac{dA}{dx} =200-2x\\when \frac{dA}{dx} =0\\200-2x=0\\x=100\\\frac{d^2A}{dx^2} =-2$

Buddy ran the same distance each day for 5 days.

bagirrra123 [75]

Answer:

One expression you can do is the total amount of distance Buddy runs in a 5 day period, as a function of the amount of miles he runs in a day.

d(x) = y = 5x

d(x) being total amount of miles buddy runs in 5 days. x being the amount of miles he runs in a day.

Now if he ran 10 miles a day, just substitute 10 for x.

d(10) = y = 5(10) = 50
