Factor the expression completely.
evablogger [386]

Answer:

Factoring the expression xy^4+x^4y^4 completely we get \mathbf{xy^4(x+1)(x^2-x+1)}

Step-by-step explanation:

We need to factor the expression xy^4+x^4y^4 completely

We need to find common terms in the expression.

Looking at the expression, we get xy^4 is common in both terms, so we can write:

xy^4+x^4y^4\\=xy^4(1+x^3)

So, taking out the common expression we get: xy^4(1+x^3)

Now, we can factor the term (1+x^3) or we can write (x^3+1) by using formula:

a^3+b^3=(a+b)(a^2-ab+b^2)

So, we get:

xy^4(1+x^3)\\=xy^4(x^3+1)\\Applying\:the\:formula\;of\:a^3+b^3\\=xy^4(x+1)(x^2-x+1)

Therefor factoring the expression xy^4+x^4y^4 completely we get \mathbf{xy^4(x+1)(x^2-x+1)}

HELP PLZZZ!!!! What is the approximate area of a circular pond?
Georgia [21]

Answer:

<h2>B. 49,062.5 ft²</h2>

Step-by-step explanation:

The formula of an area of a circle:

A=\pi r^2

r - radius

We have the diameter d = 250 ft. We know: d = 2r.

Therefore r = 250 : 2 = 125 ft.

Substitute:

A=\pi(125)^2=15625\pi

\pi\approx3.14\to A=(15625)(3.14)=49062.5\ ft^2
