Answer:

Option A. ( 9x³ - 2x - 3 )

Step-by-step explanation:

Given polynomials are ( 6x³ - 8x - 5 ) and ( 3x³ + 6x + 2)

We have to find the sum of these polynomials

( 6x³ - 8x - 5 ) + ( 3x³ + 6x + 2)

We will collect the similar terms first.

6x³ - 8x - 5 + 3x³ + 6x = 2

= ( 6x³ + 3x³ ) + ( 6x - 8x ) + ( 2 - 5 )

= ( 9x³ - 2x - 3 )

Option A. ( 9x³ - 2x - 3 ) is the correct option.

Ach equation:<br> - 5(– 2x - 4) + 5x - 4 =- 29
Zinaida [17]

- Multiply (-2x-4) by -5:

[(-5)(-2x) + (-5)(-4)] +5x - 4 = -29

= 10x+20+5x-4=-29

- Combine Like Terms:

(10x+5x) + (20-4) = -29

15x+16=-29

- Subtract 16 from each side

15x+16 -16 = -29 -16

15x = -45

x = -3

bija089 [108]
2x - 13 = 33 \\ 2x = 33 + 13 \\ 2x = 46 \\ \frac{2x}{2} = \frac{46}{2} \\ x = 23
33-23=10. 10+23=33. 23-10=13
the numbers are 23 and 10
