Answer:
The Associative Properties of Addition
Step-by-step explanation:
The associative property of addition tells us that numbers' order can be switched around without altering the final result.
If the planes are parallel to one another then they will never intersect (assuming they are distinct planes as the question states).
Otherwise they will intersect along a single line.
Therefore the answer is NEVER - they can never intersect in a pair of lines.
To simplify the expression stated, it is better to write it in the numerical form. The statement is:
<span>quantity 12 x plus 36 over quantity x squared minus 4 x minus 21
The numerical form is:
12x+36 / (x</span>²-4x-21)
Simplifying,
12x+36 / (x<span>²-4x-21)
</span>12 (x+3) / (x+3)(x-7)
We can cancel the x+3 term, leaving only:
12/(x-<span>7)</span>
