Answer: 113.1

Step-by-step explanation:

Diameter = 12

We must find the radius. To do so, we divide the diameter by 2.

Radius = 6

Formula for finding the area of a circle: πr²

π = 3.14159265359

3.14159265359 × 6²

6 × 6 = 36

3.14159265359 × 36 = 113.097335529

Rounded to the nearest tenth = 113.1

Select the correct answer.

Answer:

D) x² -x - 10 =0

Step-by-step explanation:

Given that

$\frac{2}{3x-6} - \frac{1}{3x+6} = \frac{1}{3}$

L.C.M

$\frac{2(3x+6)-(3x-6)}{(3x+6)(3x-6)} = \frac{1}{3}$

$\frac{(6x+12-3x+6)}{(3x+6)(3x-6)} = \frac{1}{3}$

$\frac{(3x+18)}{((3x)^{2} )-(6)^{2} } = \frac{1}{3}$

⇒ $3(3x+18) = 9 x^{2} - 36$

⇒ 9 x + 54 = 9 x² - 36

⇒ 9 x² - 36 - 9x - 54 =0

⇒ 9 x² - 9x - 90 =0

⇒ 9(x² -x - 10 ) =0

⇒ x² -x - 10 =0

Which expression is NOT equivalent to 8 times −5 and 1/4?<br><br> Drag this expression to the box.

timurjin [86]

The correct answer is 8×(-6) - 8×3/4.

Simplifying this problem is the same as the problem 8× - 6 3/4, not 8× -5 1/4.
