Answer:

Step-by-step explanation:

You will need to foil in order to get the correct answer.

3x * 2x = 6x^2

3x * -3 = -9x

-4 * 2x = -8x

-4 * -3 = 12

Combine like terms:

-9x + -8x = -17x

Now rewrite the answer with the simplified terms:

6x^2 - 17x + 12

And there's your answer!

If 18 is added to a certain number and the sum is divided by 6, the result is 1 more than 14 of the original number. Find the or

Katyanochek1 [597]

The original number is 72

(18+x)/6 = 1+14
1/6x + 3 = 1 + 14 (Distribute)
1/6x + 3 = (1+14) (Combine Like Terms)
1/6x + 3 = 15
- 3 = -3 (Subtract 3 From Both Sides)
1/6x = 12
(1/6x)*6 = 12 * 6 (Multiply Both Sides By 6)
x = 72

Let f(x) = 8x3 − 28x + 61 and g(x) = 2x + 5. Find f of x over g of x.

antoniya [11.8K]

Answer:

$4x^2-10x+11+\frac{6}{2x+5}$

Step-by-step explanation:

The given functions are:

$f(x)=8x^3-28x+61$ and $g(x)=2x+5$

By algebraic properties of functions;

$\frac{f(x)}{g(x)}=\frac{8x^3-28x+61}{2x+5}$

We perform the long division of the two polynomials as shown in the attachment.

Therefore:

$\frac{8x^3-28x+61}{2x+5}=4x^2-10x+11+\frac{6}{2x+5}$

The last choice is correct
