Do you mean a_(n+1), worded a sub (n+1)?
If so yes. If the function of the sequence is getting smaller or more negative with each term.
The property used in #20 was called 'the distributive property'.
This property gets rid of the parenthesis and also gets the expression more simple.
x(y+b)
x*y + x*b ⇔ Notice the change here?
Answer would be: Distributive property
We have the supplementary angles.
The sum of the measures of the two Supplementary Angles is 180°.
Therefore we have the equation:
13x - 2 + 39 = 180
13x + 37 = 180 <em>subtract 37 from both sides</em>
13x = 143 <em>divide both sides by 13</em>
<em>x = 11</em>
<h3>Answer: 11</h3>
Missing: 360 | Must include: 360
