aniked [119]

Answer:

Option a - $xy^2+5$

Step-by-step explanation:

Given : Polynomial $x^3y^2+8xy^2+5x^2+40$

To find : Select one of the factors of polynomial ?

Solution :

The polynomial $x^3y^2+8xy^2+5x^2+40$

We factor of above polynomial by taking common terms,

$xy^2(x^2+8)+5(x^2+8)$

$(xy^2+5)(x^2+8)$

From the given options,

$xy^2+5$ is one of the factors of polynomial.

Therefore, option a is correct.

Find the length of UW(with a line over it) if W is between U and V, UV = 16.8 centimeters, and VW = 7.9 centimeters.

stealth61 [152]

Answer:

8.9 cm

Step-by-step explanation:

We have
$\overline {UV} = 16.8 cm\\\\\overline {WV} = 7.9 cm\\\\ Since all lines are scalars, \overline{WV} = \overline{VW}\\\textrm{We see that \overline{UW} + \overline{WV} = \overline{UV}\\\\\overline {UW} \\ = \overline {UV} - \overline {WV} = 16.9 - 7.9 = 8.9 cm}$
