The volume of a prism is given by:

V=lwh

We know that the height is x. The length is 25 shorter than x, this can be express as:

x-25

The width is 14 longer than x, this can be express as:

x+14

Plugging the expressions for the length, the width and the height we have that:

\begin{gathered} V=(x-25)(x+14)x \\ V=x(x-25)(x+14) \end{gathered}

Therefore, the volume of the prism is:

V=x(x-25)(x+14)

What is the image point of (–7, 1) after a translation left 4 units and down 5 units?
Marizza181 [45]
<h2>Translating a Point</h2><h3>Answer:</h3>

(-11,-4)

<h3>Step-by-step explanation:</h3>

When we first translate the point (-7,1) to the left by 4 units, we just need to subtract the x-coordinate of the point by 4.

(-7 -4,1) \\ (-11,1)

Now we have the point (-11,1). We then translate it down by 5 units by subtracting the y-coordinate of the point by 5 units.

(-11,1 -5) \\ (-11,-4)

Find the 52nd term of the arithmetic sequence 5, 9, 13
IRINA_888 [86]

Answer:

209

Step-by-step explanation:

You would first create an explicit formula for the provided sequence.

The basic explicit formula for arithmetic sequences is a_{n} = d(n-1) + a_{1}, where an is the number of the term, d is the number you are adding or subtracting by, n the location of the term, and a1 is the first number.

We would then substitute the values given into the formula.  

We are trying to solve the value of the 52nd term. This makes n = 52. The first number of the sequence is 5, so a1 is 5. Finally, d is 4 because we are adding 4 to each number in the sequence.

Therefore, our resulting equation would be a_{n} =4(52-1)+5, which equals 209.

Hey can you please help me posted picture of question:)
polet [3.4K]
The given trinomial can be factored using the factorization method.
x² - 2x - 24
The middle term should be written is such a way that the sum of two terms is equal to the middle one and their product should be equal to the product of first and third term. So the above expression can be written as
= x² -6x + 4x - 24
= x(x-6) + 4(x-6)
= (x-6)(x+4)
Thus, (x-6)(x+4) is the factored form of the polynomial.
So the correct answer is option B
