Answer:
154.285
Step-by-step explanation:
The sum of the interior angles of a 14-gon = (14-2)*180 = 2,160 degrees. There are 14 vertexes (vertices) for a 14-gon. It is 'regular' so all these angles are equal. By dividing 2160 (sum of all angles) by 14 (total amount of angles) we can see how much each angle is worth. So the interior angle of each is 154.285 degrees.
Answer:
The length of this rectangle is 6 units.
Step-by-step explanation:
Let the width of the rectangle be x.
x • (x+2) = 48
x^2+2x=48
x^2+2x-48=0
x^2 - 6x + 8x - 48
x(x-6) 8(x-6)
(x+8)(x-6)
x=-8,6
You need to isolate the variable meaning .make x the only thing on one side, you do this by doing the opposite of what is being done to it. 1/2 is being added to it so subtract 1/2 from both sides of the equel sign. Next it is being multiplied by 2/3 so divide by 2/3 on both sides and you have your answer, by doing the opposite of what is being done to x you cancel everything out on that side leaving only x.
