A - 2x^2 + 2x - 2

To find this, set up the equation:

(-x^2 + 6x - 1) + ( 3x^2 - 4x - 1)

With this, you need to combine like terms while taking into consideration the addition sign.

-x^2 + 3x^2 = 2x^2
6x + - 4x = 2x
- 1 + - 1 = - 2

Hope this helps!

Find the angle of XZY

qaws [65]

Answer:

<h2>23.6°</h2>

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

<h3>to find:</h3>

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>
