You know what I think that other guy is really foul so I will answer your question for da brainliest

Step 1: (( 18 * (x^3)) + 5x^2) - 2x

Step 2: what you need to do is figure out what this equation really means but here I will tell you

The real step 1 is multiply the coefficient of the first term by the constant 18 times negative 2= negative 36

Step 2: find two factors of negative 36 whose sum is equals the coefficient of the middle term, which is 5.

-36 + 1 = -35

-18 + 2 = -16

-12 + 3 = -9

-9 + 4 = -5

-6 + 6 = 0

-4 + 9 = 5 that’s it

So your answer will be x times (9x - 2) times ( 2x + 1)
That is your answer
Hope this helped

HELP ME PLEASE!!!!

Answer:

option A

(1.5,1.2)

Step-by-step explanation:

Given in the question two equations

Equation 1

y = √x

Equation 2

y = x²- 1

Equate both equations

√x = x²- 1

<h3>1 method </h3><h3>by plotting graph</h3>

We can see from the graph that both meets when x = 1.5 and y = 1.2

<h3>2 method </h3>

we can plug the options given one by one to see which points satisfy

one thing we know is that x ≠ any negative value since

y = √x and square root of negative value is not possible

so option b and c are rejected

option A

√1.5 = y = 1.2

1.5²- 1 = y = 1.2

(g(1) = 10<br> (g(n) = g(n − 1) – 7.5<br> g(3) =

Amanda [17]

Answer:

g(3) = - 5

Step-by-step explanation:

Given

g(n) = g(n - 1) - 7.5 and g(1) = 10, then

g(2) = g(2 - 1) - 7.5 = g(1) - 7.5 = 10 - 7.5 = 2.5

g(3) = g(3 - 1) - 7.5 = g(2) - 7.5 = 2.5 - 7.5 = - 5

Find dx/dt when y=2 and dy/dt=1, given that x^4=8y^5-240<br><br> dx/dt=

katrin2010 [14]

Answer:

The value of $\frac{dx}{dt}$ is $\frac{160}{x^3}$ .

Step-by-step explanation:

The given equation is

$x^4=8y^5-240$

We need to find the value of $\frac{dx}{dt}$ .

Differentiate with respect to t.

$4x^3\frac{dx}{dt}=8(5y^4)\frac{dy}{dt}-0$ $[\because \frac{d}{dx}x^n=nx^{n-1},\frac{d}{dx}C=0]$

$4x^3\frac{dx}{dt}=40y^4\frac{dy}{dt}$

It is given that y=2 and dy/dt=1, substitute these values in the above equation.

$4x^3\frac{dx}{dt}=40(2)^4(1)$

$4x^3\frac{dx}{dt}=40(16)(1)$

$4x^3\frac{dx}{dt}=640$

Divide both sides by 4x³.

$\frac{dx}{dt}=\frac{640}{4x^3}$

$\frac{dx}{dt}=\frac{160}{x^3}$

Therefore the value of $\frac{dx}{dt}$ is $\frac{160}{x^3}$ .
