We can multiple this binomial and this trinomial to find an equivalent expression.

(x + 4)(3x^2 + 2x)

3x^3 + 2x^2 + 12x^2 + 8x

Combine like terms.

3x^3 + 14x^2 + 8x is the equivalent polynomial.

Please help I’m stuck on this question, I’ll give brainliest
Anit [1.1K]

Answer:

49.55

Step-by-step explanation:

okay so, what we do is
Get 15% of 23
Get 15% of 32

15% of 23 is 3.45

15% of 32 is 4.80

Now we do

23 - 3.45

32 - 4.80

23 - 3.45 is 19.55

32 - 4.80 is 27.2

This is the part im not 100% on

27.20 + 19.55 is 46.75

6% of 46.75 is 2.80

46.75 + 2.80 is 49.55

Now i dont know if its that way or if you apply the 6% sale tax to each individual item

Write the equation in standard form for the circle with center (0, 9) passing through (0, 27/2)
sammy [17]

Given

coordinates of center= (0,9)

Circle passes through (0, 27/2)

Find

Equation of circle

Explanation

The equation of circle in standard form is

\begin{gathered} (x-h)^2+(y-k)^2=r^2 \\ (x-0)^2+(y-9)^2=r^2 \end{gathered}

We know the circle passes through (0,27/2), then

\begin{gathered} (0-0)^2+(\frac{27}{2}-9)^2=r^2 \\ r=4.5 \end{gathered}

So the equation in the standard form is

(x-0)^2+(y-9)^2=4.5^2

Final Answer

(x-0)^2+(y-9)^2=4.5^2
