Which polynomial expression represents a sum of cubes? (6 – s)(s2 + 6s + 36) (6 + s)(s2 – 6s – 36) (6 + s)(s2 – 6s + 36) (6 + s)

Nadusha1986 [10]

Answer:

Option 3 is correct that is $(6+s)(s^2-6s+36)$

Step-by-step explanation:

We have general formula for sum of cube which is

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

Here, we have a=s and b=6

on substituting the values in the formula we will get

$6^3+s^3=(6+s)(s^2+6^2-6s)$

After simplification we will get

$6^3+s^3=(6+s)(s^2+36-6s)$

After rearranging the terms we will get

$6^3+s^3=(6+s)(s^2-6s+36)$ which exactly matches option 3 in the given options.

Therefore, option 3 is correct that is $(6+s)(s^2-6s+36)$

Find the angle of XZY

qaws [65]

Answer:

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>

trigonometry i.g sin(x)=opp/hypo
PEMDAS

<h3>given:</h3>

opp:6
hypo:15

xyz angle

<h3>let's solve:</h3>

$let \: xyz \: angle \: be \: \alpha$

$according \: to \: the \: question$

$\sin( \alpha ) = \frac{xy}{zy}$

$\sin( \alpha ) = \frac{6}{15}$

$\alpha = asin( \frac{6}{15} )$

$\alpha = {23.6}^{o}$

therefore

<h3>xyz angle=23.6°</h3>
