Answer:

A) l = 2 * w

B) 131 = 2l + 2w

B) 2l = 131 -2w

B) l = 65.5 -w

Substituting this into A)

65.5 -w = 2w

3w = 65.5

width = 21.8333333333

length = 43.6666666666

Double - Check

131 = 2 * 21.833333333 + 2 * 43.6666666666

131  = 43.6666666  + 87.33333333

131 = 131

<h3>\boxed{ \boxed{ \bold{ {x}^{2}  + 4x - 21}}}</h3>

Step-by-step explanation:

\sf{(x - 3)(x + 7)}

Use the distributive property to multiply each term of the first binomial by each term of the second binomial.

⇒\sf{x(x  + 7) - 3(x + 7)}

⇒\sf{ {x}^{2}  + 7x - 3x  - 21}

Collect like terms

⇒\sf{ {x}^{2}  + 4x - 21}

It has a range of 0 to 1 , where 0 indicates uncertainty and 1 indicates certainty.

It is given that

The alcoholics that need professional help to stop drinking is 72.7 %

Therefore the probability of this is 72.7 /100 = 0.727

The probability that they will not need professional help is given by

q = 1 - p

q = 0.273

Therefore the probability that a random alcoholic can kick the habit without professional help is 0.273 .
