Factor x^2-5x-24 i need help to figure this out

Mathematics
1 answer:
Mrac [35]2 years ago
3 0

Answer:

(x-8)(x+3)

Step-by-step explanation:

1) Find out what are the factors of the constant?

2) Which of those add to equal the coefficient before the x value?

In this particular equation, we have the constant being 24. The first two factors that come to mind are 6 and 4, and 8 and 3. Since it is -24, we need one of these numbers to be negative.

Let's look at our "b" value, or the coefficient behind the x value, 5. Looking at our factors and thinking of addition (since one of them must be negative, it will most likely be subtraction instead of addition) I can see that

8+ −3=5

which is one of the factors of -24.

This means that we can factor our equation using these numbers, getting us the following:

(x−3)(x+8)

Hope this helped!

What is the value of x in the right triangle below? Show your work and round your answer to the nearest hundredth. ​
navik [9.2K]

The length of the hypothenuse or the value of x is equal to 19.53

Data;

  • hypothenuse = x
  • adjacent = 11.2
  • opposite = 16
<h3>Pythagoras's Theorem</h3>

To solve this problem, we have to use Pythagoras's theorem which is used to find the missing side in a right angle triangle if we have at least two sides.

The formula for this is

x^2 = y^2 + z^2\\

Let's substitute the values and solve for the missing side

x^2 = 16^2 + 11.2^2 \\x^2 = 256 + 125.44\\x^2 = 381.44\\x = \sqrt{381.44} \\x = 19.53

The length of the hypothenuse or the value of x is equal to 19.53

Another United States traveler arrives at a United States point of entry. He has purchased a Flat car abroad that cost him
mart [117]

Answer:

The duty he has to pay is  156.25$.

Step-by-step explanation:

We know that for foreign-made vehicles imported into the U.S., whether new or used, either for personal use or for sale, are generally dutiable at the following rates: Cars: 2.5%.

From task we know that the  Fiat car abroad that cost him $6,250.

We have the following proportion:

100:6250=2.5:x\\\\100x=2.5\cdot 6250\\\\100x=15625\\\\x=156.25\\

The duty he has to pay is  156.25$.

Residents of the town of Maple Grove who are connected to the municipal water supply are billed a fixed amount monthly plus a ch
jekas [21]

Answer:

The exact charge per cubic foot of water usage is 4 Cents.

Step-by-step explanation:

Let the per cubic foot charge be $ 'x' and the fixed charge be $ 'y'.

A household using 1100 cubic feet was billed $ 114.

Therefore, we get the equation,

1100 x + y = 114.......( A )

And other household 1500 cubic feet was billed $ 130.

Therefore, we get the equation,

1500 x + y = 130 ......( B ).

Now, we subtract equation A from  equation B.

1500 x + y = 130.....( B )

1100 x + y = 114 ......( A )

__________________

So, we get,

400 x = 16.

Therefore,

x = \frac{16}{400}

x = 0.04 = 4 Cents.

So, the exact charge per cubic foot is 4 Cents.
