Answer: 2/x+4x^2

Step-by-step explanation:

Do distrubitive property.

SO mutiply 2/5 to 5/x which is 10/5x or 2/x

then 2/5 times 10x^2

10*2/5=20/5 or 4

Done.

Have a nice day! :)

What is the quotient of the polynomials shown below? (12x^3+14x^2 +9)÷(2x+3)

Phoenix [80]

Answer:

Option D is correct.

Step-by-step explanation:

We need to find the quotient of the polynomials:

$(12x^3+14x^2 +9)\div(2x+3)\\$

The division is shown in the figure attached.

The quotient is: 6x^2-2x+3

The remainder is: 0

So, Option D is correct.

Evaluate the function found in the previous step at X =-3

babunello [35]

$x-5y=-4x-2y$

In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.

$-3-5y=-4(-3)-2y$

Multiply -4 and -3 in the function above.

$-3-5y=12-2y$

Add 3 on both sides of the equation.

$-3-5y+3=12-2y+3$ $-5y=15-2y$

Add 2y on both sides of the equation.

$-5y+2y=15-2y+2y$ $-3y=15$

Divide both sides of the equation by -3.

$\frac{-3y}{-3}=\frac{15}{-3}$ $y=-5$

Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.

Answer:

f(-3) = -5

If the circumference of a circle measures 3/4 π cm, what is the area of the circle in terms of π?

Vinil7 [7]

$\bf \textit{circumference of a circle}\\\\
C=2\pi r~~
\begin{cases}
r=radius\\
-----\\
C=\frac{3\pi }{4}
\end{cases}\implies \cfrac{3\pi }{4}=2\pi r
\\\\\\
\cfrac{3\pi }{4(2\pi )}=r\implies 
\boxed{\cfrac{3}{8}=r}\\\\
-------------------------------\\\\
\textit{area of a circle}\\\\
A=\pi r^2\qquad \qquad \implies A=\pi \left( \boxed{\frac{3}{8}} \right)^2\implies A=\pi \left( \cfrac{3^2}{8^2} \right)
\\\\\\
A=\cfrac{9\pi }{64}$
