What is the quotient?

Mathematics
1 answer:
elixir [45]3 years ago
5 0

Answer:

Choice B is the answer.

Step-by-step explanation:

We have given an expression.

\frac{2y^{2}-6y-20 }{4y+12} ÷ \frac{y^{2}+5y+6 }{3y^{2}+18y+27 }

We have to find the quotient of the given expression.

\frac{2y^{2}-10y+4y-20 }{4(y+3)} ÷ \frac{y^{2}+2y+3y+6 }{3(y^{2}+6y+9) }

\frac{2y(y-5)+4(y-5)}{4(y+3)} ÷ \frac{y(y+2)+3(y+2)}{3(y^{2}+3y+3y+9) }

\frac{(2y+4)(y-5)}{4(y+3)} ÷ \frac{(y+2)(y+3)}{3(y+3)(y+3)}

By changing distribution into multiplication, we have

\frac{2(y+2)(y-5)}{4(y+3)} × \frac{3(y+3)(y+3)}{(y+2)(y+3)}

\frac{3(y-5)}{2} which is the answer.

Exponential form of xyyzzz
Trava [24]

Answer:

  xy²z³

Step-by-step explanation:

An exponent is a way to indicate the number of times the factor is repeated. When it is 1, it is rarely shown.

  x is repeated once, so will appear without an exponent

  y is repeated twice, so will have an exponent of 2

  z is repeated 3 times, so will have an exponent of 3

__

  xyyzzz = xy²z³

_____

In plain text, an exponent is indicated with a caret (^).

  xy^2z^3

The sum of the lengths of two opposite sides of the circumscribed quadrilateral is 10 cm, and its area is 12 cm2. Find the radiu
PtichkaEL [24]

Answer:

1.2 cm

Step-by-step explanation:

The area of sircumscribed quadrilateral over a circle is equal to

A=s\cdot r,

where s is semi-perimeter of the quadrilateral and r is the radius of the circle.

Use property of circumscribed quadrilateral: The sums of the opposite sides are equal.  

So, if the sum of two opposite sides of the circumscribed quadrilateral is 10 cm, then the sum of another two sides is also 10 cm and the perimeter of the quadrilateral is 20 cm. Hence,

s=\dfrac{20}{2}=10\ cm

Now,

A=s\cdot r\\ \\12=10r\\ \\r=\dfrac{12}{10}=1.2\ cm
