8x^4-2x+2

5x^7x-7

I know you're going to question how I got 7. & the answer is when you have to negatives by each other that turns into a positive and you actually add. Hope this helps!

If:<br> AC=26,<br> BC=7x + 2, and<br> AB = 9x + 8<br> Find BC!
Bond [772]

Answer:

BC = 9

Step-by-step explanation:

Given AC = 26

BC=7x + 2

AB = 9x + 8  

Since BC and AB are two parts of AC. Therefore we can write in the following form.

AC = AB +BC

Now insert the given values in the above formula.

26 = 9x + 8 + 7x + 2

26 = 16x + 10

26 – 10 = 16x

16 = 16x

x = 16 / 16  

x = 1

Now insert x = 1 in BC=7x + 2

BC = 7 (1) + 2

BC = 9

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)_{}

a company manufactures rectangular cardboard boxes. each box is 20 inches long and 15 inches wide. the heights of the boxes rang
Bogdan [553]

The range of possible values for the volume of the boxes would be 1200 - 1800 cubic inches

The dimensions of the rectangular cardboard boxes are given as

Case I

Length = 20 inches

breadth = 15 inches

Height = 4 inches

Volume of the rectangular cardboard box in case I = Length x breadth x breadth

= 20 x 15 x 4

= 1200 cubic inches

Similarly,

Case II

Length = 20 inches

breadth = 15 inches

Height = 6 inches

Volume of the rectangular cardboard box in case I = Length x breadth x breadth

= 20 x 15 x 6

= 1800 cubic inches
