Please help! 3 Questions please show how you solved the problem
Masteriza [31]

Answer:

1)  (-y^2-4y-8+4y^2+6y-3)

2)  32x^5y^4z^2

3)  x^3-9x^2+14x+24

Step-by-step explanation:

Given the expression we have to simplify the expression

1)   (-y^2-4y-8)-(-4y^2-6y+3)

⇒ (-y^2-4y-8+4y^2+6y-3)

Combining like terms, we get

⇒ 3y^2+2y-11

2.)    (2x^2y^3z^2)(4xy.4x^2)

⇒ (2x^2y^3z^2)(16x^3y)

⇒ 32x^5y^4z^2

3.)   (x-4)(x^2-5x-6)

⇒ x^3-5x^2-6x-4x^2+20x+24

⇒ x^3-9x^2+14x+24

HELP PLEASE I honestly need help please help

Answer:

  5.  x = 160; y = 20

  6.  h = 125°; g = i = 55°

Step-by-step explanation:

Vertical angles are found on opposite sides of a point where lines cross. Each angle is formed from rays opposite those of the other angle. Vertical angles are congruent.

5. x° and 160° are vertical angles: x° = 160°

  y° and 20° are vertical angles: y° = 20°

__

6. h° and 125° are vertical angles: h° = 125°

The angles g° and 125° form a "linear pair" so total 180°.

  g° = 180° -125° = 55°

  g° and i° are vertical angles: g° = i° = 55°
