This is the associative property, since any numbers can <em>associate </em>with each other, via the parentheses.

Answer:

46.25%

Step-by-step explanation:

First, add both numbers together. (86 + 74).

Next, we have 160. And that is 100%.

Now, we have to find what 74 is compared to 160.

74 is 46.25% of 160.

There's our answer.

$3x^2-3x-6=0\\
3(x^2-x-2)=0\\
x^2-x-2=0
x^2+x-2x-2=0\\
x(x+1)-2(x+1)=0\\
(x-2)(x+1)=0\\
x=2 \vee x=-1
$
