Divide x^3-3x^2-10x+24 by x-2
melisa1 [442]
You can do this using synthetic division, which is the easiest way.  If x - 2 = 0, then x = 2.  That 2 will go outside the "box" and the leading coefficients of the terms in the polynomial will go inside the "box".  2    (1   -3    -10    24).  Bring down the first number, the 1.  Multiply that 1 by the 2 to get 2.  Put that 2 up under the -3 and add to get -1.  Multiply that -1 by the 2 to get -2.  Put that =-2 up under the -10 and add to get -12.  Multiply that -12 by the 2 to get -24.  Put the -24 up under the 24 and add to get 0.  That means that x - 2 is a factor of the polynomial.  What's left, the bolded numbers, are the coefficients of a new polynomial that is one degree less than the polynomial you started with.  In other words, when we divide your polynomial by x-2, you get x^2-x-12.

the length of a sandbox is three feet longer than it’s width. Write the expression that would represent the area of the sandbox.
Rashid [163]

Part A : D.)

Part B : Length of the sandbox is 10 feet.

Step-by-step explanation:

Given,

Perimeter = 29 ft

We need to find the equation for the perimeter and also the length of the sandbox.

Solution,

Let the width of the sandbox be 'w'.

Now as per question said;

The length of the sandbox is 1 foot longer than twice the width of the sandbox.

So we can say that;

Length =

Now we know that the perimeter is equal to the sum of twice of length and width.

framing in equation form, we get;

Perimeter =

we have given the perimeter, so on substituting the value, we get;

Hence The equation used to find the width is  .

Now we solve for 'w'.

Applying distributive property, we get;

Subtracting both side by '2' we get

Dividing both side by 6 we get;

Width of the sandbox = 4.5 ft

Length of the sandbox =

Hence Length of the sandbox is 10 feet.
