Answer:

C = \pi (2x -2)

Step-by-step explanation:

The perimeter of a circle is the circumference of the circle. To find it, use the formula C = \pi d.

The diameter here is two times the radius x, d = 2x. But here it has been decreased by 2 so it becomes d = 2x - 2.

Substitute into the formula.

C = \pi (2x -2)

Solve (algebraically by any method) 3x to the 2 power +8x - 4= 0
Ratling [72]
3 x^{2} + 8x +(-4) = 0
x = <u>-b + √ b² - 4ac</u>
               2a
x = <u>-8 + √ 8² - 4(3)(-4)</u>
                 2(3)
x = <u>-8 + √64 - 48 </u>
               6
x = -<u>8 + √16
</u>           6<u>
</u>x = -<u>8 + 4 </u>      x = <u>-8 - 4</u>

Is 2/3 bigger than 3/5
alina1380 [7]
2/3 is greater than 3/5 because if you cross multiply, you'll get 10 on left side and 9 on the right, which means 3/5 is less than 2/3.
