Translate this problem to an equation and solve. the area of a swimming pool is 200 square feet. the length of the pool is 10 feet longer than the width. what is the length of the swimming pool?

The width measures 10 feet.

Let the length be x and the width be x−10.

Since the pool is rectangular:

A=L×W

200=x(x−10)

200=x2−10x

0=x2−10x−200

0=(x−20)(x+10)

x=20and−10

A negative answer is not possible, so the width of the pool is (20−10)=10 feet.

The answer is 20!

Hope this helped

i dony know

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
