3rd option ❤️❤️❤️❤️❤️❤️

x= 110; y= 12

Hi there! The third answer is correct.
x = 110
y = 12

x = 110 because angle D equals angle B.
y = 12 because the length of AB equals the length of CD.

The height of a cylinder is 3 units. Its radius is 10 units. What is the volume of the cylinder, in cubic units? (Use π = 3.14)

serg [7]

The answer would be 942.
since the formula for volume of a cylinder is the area of the base times the height you would need to multiply pi times 10^2 and then times the height of 3.

3.14 * 10^2 = 314
314 * 3 = 942

I hope this helped :)

3x^2-3x<br> ----------- -3<br> x^2-9x<br> please give me the simplified answer + explanation

STatiana [176]

You want us to simplify $\frac{3x^2-3x}{x^2-9x}-3$

first, factor top and bottom
$3x^2-3x=3x(x-1)$
$x^2-9x=x(x-9)$

so we have
$\frac{3x(x-1)}{x(x-9)}-3=$
$\frac{3(x-1)}{x-9}-3$
we want to combine fractions so multiply 3 by $\frac{x-9}{x-9}$
$\frac{3(x-1)}{x-9}-\frac{3(x-9)}{x-9}=$
$\frac{3(x-1)-3(x-9)}{x-9}=$
$\frac{3x-3-3x+27}{x-9}=$
$\frac{24}{x-9}$

the simplified answer is $\frac{24}{x-9}$
