(5x^5) - (80x^3) factoring

elena55 [62]

Answer:

Factoring the term $(5x^5) - (80x^3)$ we get $\mathbf{5x^3(x-4)(x+4)}$

Step-by-step explanation:

We need to factor the term $(5x^5) - (80x^3)$

First we can see that $5x^3$ is common in both terms

So, taking $5x^3$ common:

$(5x^5) - (80x^3)\\=5x^3(x^2-16)$

We can write $x^2-16$ as $(x)^2-(4)^2$

$=5x^3((x)^2-(4)^2)$

Now we can solve $(x)^2-(4)^2$ using the formula: $a^2-b^2=(a+b)(a-b)$

We can write:

$=5x^3((x)^2-(4)^2)\\=5x^3(x-4)(x+4)$

So, factoring the term $(5x^5) - (80x^3)$ we get $\mathbf{5x^3(x-4)(x+4)}$

600 feet of fence surround a rectangular playground that is 100 feet wide. How long is the playground? A.400 b.500 c.300 d.200

Paladinen [302]

Answer:

A.400

Step-by-step explanation:

Well perimeter for a rectangle is l+l+w+w

100+100+l+l=600

200+2l=600

Subtract 200 from both sides

2l=400

Divide both sides by 2

l = 400 feet

The length of the rectangle is 400 feet long.
