Answer:

The given expression is  simplified as : −34 (24 − 12 x)  =  -816 + 408 x

Step-by-step explanation:

The given expression is given as:

−34 (24 − 12 x)  

Now, by <u>DISTRIBUTIVE PROPERTY:</u>

A( B -C) = AB - AC

Applying the same distributive property in the given expression ,we get

−34 (24 − 12 x)  =  (-34) (24) - (-34)(12 x)

                          =  -816 + 408 x

or, −34 (24 − 12 x)  =  -816 + 408 x

Hence, the given expression is simplified as  

  −34 (24 − 12 x)  =  -816 + 408 x

Ann wants to choose from two telephone plans. Plan A involves a fixed charge of $10 per month and call charges at $0.10 per minute. Plan B involves a fixed charge of $15 per month and call charges at $0.08 per minute.

Plan A $10 + .10/minute

Plan B $15 + .08/minute

If 250 minutes are used:

Plan A: $10+$25=$35
Plan B: $15+$20=$35

If 400 minutes are used:

Plan A: $10+$40=$50
Plan B: $15+$32=$47

B is the correct answer. How to test it:

Plan A: $10+(.10*249 minutes)
$10+$24.9=$34.9

Plan B: $15+(.08*249 minutes)
$15+$19.92=$34.92

Plan A < Plan B if less than 250 minutes are used.

Scorpion4ik [409]

Answer:

A) L = W + 6

B) L * W = 167  OR L = 167 / W

Substituting B) into A)

167 / W = W + 6

Multiplying both sides by "W" we get

167 = W^2 + 6W

W^2 + 6W -167

Solving by the quadratic formula

Width = 10.266

Length = 16.266
