Aleksandr [31]

Answer:

-5x³ -5x² -9x - 4

Step-by-step explanation:

(-6x³-4x²-8)+(x³-x²-9x+4)

Add the like terms.

-6x³ and x³ are like terms. -6x³ + x³ = -5x³

-4x² and -x² are like terms. -4x² - x² = -5x²

-8 and 4 are like terms. -8 + 4 = -4

-6x³-4x²-8 +x³-x²-9x+4 = -5x³ -5x² -9x - 4

Find X and Y. can someone please help me with this question, thank you
Arturiano [62]

3<em>x</em> + 120° + <em>x</em> + 120° = 360°

4<em>x</em> + 240° = 360°

4<em>x</em> = 120°

<em>x</em> = 30°

<em>y</em> = 1/2 (3<em>x</em> - <em>x</em>)

<em>y</em> = 1/2 (90° - 30°)

<em>y</em> = 1/2 × 60°

<em>y</em> = 30°
