The correct answer is 40 bars.
In order to find this amount we have to find when the y values are worth the same. Since both equations are equal to y, we can set them equal to each other to find a time when the y values are the same.
Company A = Company B
.75x = 10 + .50x ---> Now subtract .50x from both sides.
.25x = 10 ---> Now divide both sides by .25
x = 40
When x = 40 it will cost $30 from both companies.
Angle 4 equals 34 degrees since angle 2 and 4 are opposite angles and opposite angles are congruent
Area = perimeter + 132.
Let each side of the city be x miles long, then:-
x^2 = 4x + 132
x^2 - 4x - 132 = 0
x = [-(-4) +/- sqrt((-4)^2 - 4 * 1 *-132)] / 2
x = 13.66, -9.66 We ignore the negative
So the city has dimension of 13.66 * 13.66
13.7 * 13.7 to nearest 10th
<u>ANSWER</u>

<u>EXPLANATION</u>
The given compound inequality is

We need to simplify this inequality so that we can obtain x standing alone between the inequality signs.
We add 6 through out the inequality.

This simplifies to:

We now divide through by -3 and reverse the inequality sign.

We now simplify to get:

The answer is 0.01654846336
