If you would like to simplify <span>-4 * (7x - 3y - z) - 6 - (-6) * (9x - z + 2), you can do this using the following steps:
</span>-4 * (7x - 3y - z) - 6 - (-6) * (9x - z + 2<span>) = -4 * 7x + 4 * 3y + 4z - 6 - (-6 * 9x + 6z - 6 * 2) = -28x + 12y + 4z - 6 - (-54x + 6z - 12) = </span>-28x + 12y + 4z - 6 + 54x - 6z + 12 = <span>-28x + 54x + 12y + 4z - 6z + 12 - 6 = 26x + 12y - 2z + 6
</span>
The correct result would be <span>26x + 12y - 2z + 6.</span>
Answer:
14x + 8
Explanation:
⇒ 4(5x+5) - 3(2x + 4)
distribute inside parenthesis
⇒ 4(5x) + 4(5) - 3(2x) - 3(4)
multiply the variables
⇒ 20x + 20 - 6x - 12
collect like terms
⇒ 20x - 6x + 20 - 12
subtract like term
⇒ 14x + 8
No, C is correct. 13 and 2 are prime numbers, 6 is not
