The answer is -6.833333333
Answer:
Step-by-step explanation:
2a + 6 / a² -9 = 2(a + 3) / (a² -3²)
= 2(a+3) / (a+3)(a-3) {a²-b² = (a+b)(a-b)
= 2 / (a-3)
Answer:
36
Step-by-step explanation:
the first sequence starts
4 12 (3*4) 36 (3*12) 108 (3*36) ...
the second sequence starts
20 28 (8+20) 36 (8+28) 44 (8+36) ...
so, just by writing down a few elements you can see it already.
I knew it already before that just by thinking "the first sequence has only numbers that can be divided by 3. what is the first number of the second sequence that can be also divided by 3 ? oh, yeah, 36 !"

<span>Two lines that are always the same distance apart and never touch. this is called your Parallel lines
</span><span>Two lines that do not intersect and are not parallel. this is called your Skew lines

<span>Parallel planes are found in shapes like cubes, which actually has three sets of parallel planes. this is called your Parallel planes

<span>If a line segment intersects two straight lines forming two interior angles on the same side that sum to less than two right angles, then the two lines, if extended indefinitely, meet on that side on which the angles sum to less than two right angles. this is called your Parallel postulate</span>
