Answer:

Step-by-step explanation:

g(x) = -x² - x - 1 = -1(x² +x + 1)

$(\dfrac{f}{g})(x) =\dfrac{x^{2}+x+1}{(-1)(x^{2}+x+1}\\\\=\dfrac{1}{-1} = -1$

Factorise:<br> 8 x 3 + 729 +10800² + 486X.

hjlf

Answer:

(2x+9) ^3

Step-by-step explanation:

(((8 • (x3)) + 729) + (22•33x2)) + 486x

((23x3 + 729) + (22•33x2)) + 486x

Factoring: 8x3+108x2+486x+729

8x3+108x2+486x+729 is a perfect cube which means it is the cube of another polynomial

In our case, the cubic root of 8x3+108x2+486x+729 is 2x+9

Factorization is (2x+9)3

A flying carpet flies 2.4 miles with the wind in the same amount of time it flies 1.4 miles against the wind. The wind speed is

Ainat [17]

Answer:

$15.2~mph$

Step-by-step explanation:

Let the time flown by the flying carpet be $t$ . Then, we have that $(2.4)/t=(1.4)/t+2*4$ .

We multiply both sides of the equation by $t$ to get $2.4=1.4+8t$ .

We subtract $1.4$ from both sides to get $1=8t$ .

We divide both sides of the equation by $t=1/8$ .

We know that the speed of the flying carpet in still wind is the average of the rates of the speed of the flying carpet with the wind and against the wind.

The speed with wind is $(2.4)/(1/8)=19.2$ mph.
