Answer:
7.99
Step-by-step explanation:
x^2 +3x
Let x=1.7
(1.7)^2 +3(1.7)
2.89+5.1
7.99
square meter is the SI unit of area.
Answer:
2000 players will complete the game with a perfect score.
Step-by-step explanation:
The testing phase tells us that
is the probability that a person will finish with a perfect score.
This means 1 out of 500 people will be able to finish with perfect score.
Now,
the game is given to 1,000,000 (1 million) people and how much do we expect to finish with perfect score?? Simple! It would be
the of 1 million!
We do the calculation shown below:

So, 2000 players will complete the game with a perfect score.
P = 2(L + W)
P = 28
L = 2W - 1
28 = 2(2W - 1 + W)
28 = 2(3W - 1)
28 = 6W - 2
28 + 2 = 6W
30 = 6W
30/6 = W
5 = W ....width is 5 ft
L = 2W - 1
L = 2(5) - 1
L = 10 - 1
L = 9 <=== length is 9 ft
20 - 12 = x
combine like terms, theres ur answer
