Factor 4x^3 + 40x^2 + 100x

Mathematics
1 answer:
Kruka [31]3 years ago
7 0

Answer:

4 x (x + 5)^2

Step-by-step explanation:

Factor the following:

4 x^3 + 40 x^2 + 100 x

Factor 4 x out of 4 x^3 + 40 x^2 + 100 x:

4 x (x^2 + 10 x + 25)

The factors of 25 that sum to 10 are 5 and 5. So, x^2 + 10 x + 25 = (x + 5) (x + 5):

4 x (x + 5) (x + 5)

(x + 5) (x + 5) = (x + 5)^2:

Answer: 4 x (x + 5)^2

How many times dies 11000 go into 609,000
diamong [38]
This is simply 609 000  divided by 11 000

609 000 / 11 000.         

Cancel each of the 3 zeros at the top and bottom

= 609/11

Use a calculator

= 55.3636...

So it goes in approximately 55.36 times.

To solve 49^3x = 343^2x+1, write each side of the<br> equation in terms of base<br> DONE
Nostrana [21]

Answer:

no solution

Step-by-step explanation:

49^3x = 343^2x+1

49 = 7^2 and 343 = 7^3

7^2 ^3x  = 7^3 ^2x+1

we know that a^b^c = a^ (b*c)

7^(2 *3x)  = 7^(3 *(2x+1))

7^(6x)  = 7^(6x+3)

The bases are the same so the exponents have to be the same

6x = 6x+3

Subtract 6x from each side

0 =3

This is never true so there is no solution

Use Vocabulary in Writing
AleksAgata [21]

Answer:

Step-by-step explanation:

So you know that m= \frac{y}{x}. To find that you need to take one y(6) coordinate and subtract the other y(-2) coordinate. So then you put that in the nominator. Then you take the x(2) coordinate from the same pair that you started with the y(6) coordinate and subtract the other x(0). You put that answer in the denominator. That's how you find slope=m. Then you plug slope in the equation.

y = \frac{8}{2} x + b

Then you take on y coordinate and plug it into y.

6 = 4 x + b

Then you insert the x coordinate from the same pair that you did y.

6  = 4(2) + b

Now 4 times 2 is 8 and 8 is not equal to 6. So b must be -2.

You can check it with the other coordinates, and that's how you check your original answer.

I'm in 7th grade hope you found it helpful.
