Someone know how to do this?: 6x2+18x=0

Crazy boy [7]

The answer to the question is: Yes.

Explanation: It can be solved by following exactly the same procedures
that solved the other two questions that you posted within the past 15 minutes.

Since I'm here already, here is the solution to this one:

6x² + 18x = 0

Divide each side of the equation by 6 :

x² + 3x = 0

Factor the left side:

x(x+ 3) = 0

This statement is true if x=0 or if x=3.

The solution to this one is even the same as the solution to the last one you posted.
You really ought to take a break, go back, review the solutions you've been given,
and try to solve a few on your own.

Dmitry [639]

Answer:

2 hrs, 24 min

Step-by-step explanation:

Sally: in one hour, she can paint 1/4 of the room.

Joe: in one our, he can paint 1/6 of the room

Hour one: 1/4+1/6=3/12+2/12=5/12

1÷5/12=1*12/5=12/5

12/5= 2 & 2/5 hours, or 2.4 hours, or 2 hrs 24 minutes

( h -3 )2 for h = 5 what is it

Nookie1986 [14]

Answer: $4$

Step-by-step explanation:

Substitute the value of the variable into the equation and simplify.

I evaluate and found the exact value: 4

$( h -3 )2 \\h = 5$

If you want me to Find the Linearization at h=5: Use the formula $L(x)=f(a)+f'(a)$ $(x-a)$ to find the linearization.

Answer(Find the Linearization at h=5): $L(x)=2x-6$

Please help!!! I’m so bad at math.

marishachu [46]

Answer:

x = - 9 , 6

Step-by-step explanation:

The given function is

$h(x) = \frac{x - 8}{x^{2} + 3x - 54}$

⇒ $h(x) = \frac{x - 8}{(x - 6)(x + 9)}$

Therefore, the value of h(x) will be undefined for the denominator equal to zero.

So, (x + 9)(x - 6) = 0

⇒ x = - 9 and x = 6

Therefore, the values of x which are not in domain of function h(x) are x = - 9 , 6. (Answer)

Solve the problem.When exposed to ethylene gas, green bananas will ripen at an accelerated rate. The number of days for ripening

Alex Ar [27]

The table and the plotted data are in the attachment.

Answer and Step-by-step explanation: A line of best fit is the best approximation of the given data. It is used to show the relation of two variables and it can be determined, more accurately, by the Least Square Method.

To use the method, follow the steps:

1) Calculate the mean of the two variables:

$X = \frac{\Sigma x_{i}}{n}$
