Well u do 31.2 x 18 which is 561.6 then u divide by 2 because the formula for a triangle is base x height divided by 2 so It is 280.8
Let w and 2w-5 be the width and length. Then:
w(2w-5)=33
2w²-5w-33=0
(2w-11 )(w+3 )=0
w=11/2 or -3
If the width is 11/2 yd, then the length is 6 yds

52.56 is your answer(would have gave'n you a explanation but hey i'm sure you'll get it ^_^)
Answer:
The gambler's expected value if he makes the bet is $45.
Step-by-step explanation:
Expected value:
15% probability of a profit of $2000.
100 - 15 = 85% probability of having to pay $300, that is, a loss of $300.
The expected value is each outcome multiplied by it's probability, so:

The gambler's expected value if he makes the bet is $45.
The correct choice is C .
