I'll help with number 5 since number 4 is a bit too small and squished to read.

Check out the attached image below for the full two-column proof. The added entries are in red.

The given statement is basically what the teacher shows at the top of the problem, which is the fact that angle 5 and angle 2 are congruent. You just repeat this statement.  

The reason for statement 2 is that angle 2 and angle 4 are vertical angles. They are opposite angles formed by a pair of intersecting lines. This is the vertical angle theorem at work. We'll use the vertical angle theorem again for statement 4 when we say that angle 5 and angle 8 are the same measure.

The transitive property comes into play when we connect angles 2, 5, and 4 together, which helps us get line 3. We also connect angles 4, 5 and 8 together to get the last line, which is why the reason for statement 5 is "transitive property"

2nd term of (2r-3s)^12
earnstyle [38]

Answer:

1.-12*(2r)^11 * (3s)

= -12*2048*3 r^11 s

= -73728 r^11 s

2.12C1 (2r)¹¹(-3s) = -36(2¹¹)r¹¹s = -73728r¹¹s

3.24 r - 36 s

The second term: -36 s

4.(2r-3s)^12

= (2r)^12 + 12C1 (2r)^11 (-3s)

= 2^12 r^12 + (12) 2^11 r^11 (-3) s

= 4096 r^12 - (12)(3)(2098) r^11 s

= 4096 r^12 - 73,728 r^11 s + .....

-73,728 r^11 s

Simplify.
vazorg [7]

Answer:

9a^2sqrt(ab)

Step-by-step explanation:

The first noticable thing is that 81 has a perfect square of 9.

So it is now 9sqrt(a^5b)

you can split the a^5, to a^4 × a.

you can now take the sqrt of a^4, which is a^2, and pull it out from the sqrt

You are now left with 9a^2sqrt(ab)
