DF=14. Because DE is half the line and EF is the other half the line you add up both the lengths to get the length of whole line.

Help!!! Divide the polynomial by 7x

HACTEHA [7]

Answer:

$4x^4-9x^3+x^2$

Step-by-step explanation:

Dividing the polynomial by 7x means dividing each term by 7x, as shown below:

$\frac{28x^5-63x^4+7x^3}{7x}\\=\frac{28x^5}{7x}-\frac{63x^4}{7x}+\frac{7x^3}{7x}\\=4x^4-9x^3+x^2$

In dividing, we also used the property of exponents, shown below:

$\frac{a^x}{a^y}=a^{x-y}$

So the answer is: $4x^4-9x^3+x^2$
