Answer 1

here is your answer

Answer 2

Answer : - 29 x +9

Step by step explanation :

$x \times 2 + x - 6x \times 2 - 4x \times 2 - 9x \times 2 + 6x + 9x$

Use the commutative property to reorder the terms

$= > 2x + x - 6x \times 2 - 4x \times 2 - 9x \times 2 + 6x + 9$

Calculate the product by multiplying the numbers. Multiplying a negative and a positive equals a negative (-) × (+) = (-).

$= > 2x + x - 12x - 8x - 18x + 6x + 9$

Collect like terms by calculating the sum or difference of their coefficients.

$= > - 29x + 9$
