F( x ) = 9 x 3 + 2 x 2 ? 5 x + 4 and g ( x ) = 5 x 3 ? 7 x + 4 . what is f ( x ) ? g ( x ) ? show all of your steps and write your final answer in factored form.

The final answer is 2x(2x²+x+1)

Step-by-step explanation:

f(x)=9x³+2x²-5x+4 and g(x)= 5x³-7x+4.

We have to find f(x)-g(x).

To find f(x)-g(x) simply subtract g(x) from f(x)

(9x³+2x²-5x+4) - (5x³-7x+4)

Keep one thing in your mind that when when we subtract the expressions, signs of second bracket also gets multiplied by the negative sign which is outside the bracket.

Open the brackets for solution.

9x³+2x²-5x+4 - 5x³+7x-4

Now combine the like terms:

(9x³- 5x³)+2x²+(7x-5x) +(4-4)

4x³+2x²+2x

Now take out the common factor:

2x(2x²+x+1)

Thus the final answer is 2x(2x²+x+1)

the final answer is 2x(2x²+x+1) :)

i took the test and this is the final answer

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
