Answer: x = 0; x=10

Step-by-step explanation:

\frac{x+2}{x-4} *\frac{3x}{x+4}\\ \\x+2(x+4) = x-4(3x)\\x^{2} +2x+ 4x + 8 = 3x^{2} -12x\\2x+4x+12x =3x^{2} - x^{2} \\20x= 2x^{2} \\10x = x^2\\x=0\\x=10

Hope this helps!

a line passes through the point -2 and five and has a slope of 2/3 points A(x,3) and B(-2,y)lie on the line
olasank [31]
A and B lie on the line, yes, but what specifically are you supposed to do?  Looks like your problem statement was cut off before you'd finished typing it in.

You say your line passes thru (-2,5) and has a slope of 2/3?  Then, using the point-slope formula,

y-5 = (2/3)(x+2)  This is the general equation for your line.

Now let's play around with B(-2,y).  Suppose we subst. the x-coordinate of B, which is -2, into the equation   y-5 = (2/3)(x+2); we get y-5 = (2/3)(-2+2) = 0.  This tells us that y must be 5.  But we already knew that!!

So, please review the original problems with its instructions and this discussion and tell me what you need to know from this point on.

The radius is 10 units, and each layer is one unit high. What is the volume of the cylinder in cubed units?​
alexandr1967 [171]

Answer:

Volume of cylinder is 6285.71 square units.

Step-by-step explanation:

Given the radius of cylinder 10 units. The height is twice its radius. we have to find its volume.

r=10 units

⇒ Diameter, d = 20 units

Also given height is twice its radius.

⇒ Height=2(r)=2(10)=20 units

<h2><em><u>Volume of cylinder=πr^2h</u></em></h2>

= 22/7 × 100×20

=22/7 × 2000

= 44000/7

= 6285.71square units.

hence, volume of cylinder is 6285.71 square units.
