Please solve the following question!!

Komok [63]

2(21x − 7) + 4(3x + 2) = 6(2x + 9) + 3
42x - 14 + 12x + 8= 12x + 54 + 3
54x - 6= 12x + 57
54x=12x + 63
42x=63
x= 63/42
x= 3/2

The circles are identical. What is the circumference of each circle? Circle 1: radius of 2x; Circle 2: diameter of 2x+3. A. 3/2

Delicious77 [7]

Answer:

C=6π

Step-by-step explanation:

It is given that, two circles are identical. The radius of first circle is 2x and the diameter of other circle is 2x+3.

If identical, it means that the radius of both circles are same i.e.

$2x=\dfrac{2x+3}{2}\ \ (\because\ r=\dfrac{D}{2}, d=\text{diameter})\\\\4x=2x+3\\\\2x=3\\\\x=1.5$

Radius of both circles is 2(1.5)=3

The circumference of a circle is given by :

$C=2\pi r\\\\C=2\pi (3)\\\\C=6\pi$

So, the circumference of each circle is 6π.

The surface area (SA) of a cube with a as the length of each of its sides is given by the formula SA=6a^2 If the surface area is

slava [35]

So to rewrite it so that we can find the side, we just need to isolate the a variable.

$SA=6a^2$

So firstly, divide by 6 on both sides of the equation: $\frac{SA}{6} =a^2$

Next, square root each side, and your answer should be $\sqrt{\frac{SA}{6}} =a$
