Good morning

______

Answer:

w=12 feet

L =3×12=36 feet

Step-by-step explanation:

w×L=432 ⇔ w(3w) = 432 ⇔ 3w² = 432 ⇔ w² = 432÷3 = 144

Then  w = √(144) = 12.

Model subtraction of fraction:
cricket20 [7]
The entire race is 1 full race.
One full race is 1.
He ran 3/8 of 1, so he ran 3/8.
He needs to run the rest of the race.
The rest is unknown, so we call it x.
When you add 3/8 to the unknown, you get the full race.
The equation is

x + 3/8 = 1

Change 1 to a denominator of 8.

x + 3/8 = 8/8

Subtract 3/8 from both sides.

x = 5/8

Answer: He still needs to run 5/8 of the race.
