4(2x + 3) = 5x + 3x - 6

Likurg_2 [28]

Answer:

No solution.

Step-by-step explanation:

$4\left(2x+3\right)=5x+3x-6\\4\left(2x+3\right)=8x-6\\4\left(2x+3\right)\\(a=4,\:b=2x,\:c=3)\\=4\cdot \:2x+4\cdot \:3\\=8x+4\cdot \:3\\=8x+12\\8x+12=8x-6\\8x+12-12=8x-6-12\\0=-18$

If the final answer is 0 and both sides of this equation are unbalanced, that means there will be no solution.

Given the points (-2, 0), (-1,0), (0, – 8), (2, 0), write the polynomial in factored form.

Ket [755]

As per given by the question,

There are given that four point.

The point is,

$(-2,\text{ 0), (-1, 0), (0, -8), (2, 0)}$

Now,

From given point,

$(-2,\text{ 0), (-1, 0), (0, -8), (2, 0)}$

Then, the factor is,

$(x+2)(x+1)(x-2)$

Now, solve the above equation,

$(x+2)(x+1)(x-2)$

The factorial formd will be,

$y=a\times(x+2)\times(x+1)\times(x-2)$

Now, find the value of "a" with the help of given point (0, -8).

So,

Puth the value of x =0, and y=-8 in above equation,

Then,

$\begin{gathered} y=a\times(x+2)\times(x+1)\times(x-2) \\ -8=a\times(0+2)\times(0+1)\times(0-2) \\ -8=a(2)(1)(-2) \\ a=\frac{-8}{-4} \end{gathered}$

Then, a=2.

Now,

The value of a is 2.

And,

The polynomial in the factored form is,

$y=2(x+2)(x+1)(x-2)$

Hence, the value of a is 2 and the polynomial in the factored form is,

$y=2(x+2)(x+1)(x-2)_{}$

PLEASE HELP AND HURRY!

Kamila [148]

Answer:

ANSWER BELOW

Step-by-step explanation:

If the door is 9 x 2 ft (18 sq ft):

12 x 18 = 216 sq ft. (Front face including the door)

216 sq ft - 18 sq ft = 198 (Front face not including the roof or door)

For the roof, the formula is h b/2:

So if the height is 4 and the base is 18, the area of the roof is 36.

To find the total area, you must add the area of the front face and the roof (without the door).

198 + 36 = 234 sq ft

Have a wonderful day my friend!

The graph of a rational function has vertical asymptote at x=-3 and x=3 and a horizontal asymptote At y=1.write a function that

liubo4ka [24]

Answer:

1/(x^2-9) + 1.

Step-by-step explanation:

It will be a fractional function with the denominator = 0 when x = 3 or -3.

Therefore the denominator could be x^2 - 9.

At high and low values of x the function will have an horizontal asymptote at y = 0 so to get an asymptote at x = 1 the function could be

1/ x^2-9) + 1.
