Answer:

[130-5(13)] (13) = $845   max revenue.

Step-by-step explanation:

If the number of books sold = 130-5p      then revenue will be   (130-5p)p = -5p^2+130p

the maximum can be found by graphing or by the fact that the max will be   -b/2a   =   -130/-10 = 13 dollars/book

 

[130-5(13)] (13) = $845   max revenue.

State what additional information is required in order to know that the triangles are congruent by SAS
zalisa [80]
<h3>You are correct. The answer is the second choice.</h3>

BC = JC by the single tickmarks shown

CD = CD because of the reflexive property

The angles between these two pairs of sides, that you've marked in the second answer choice, are needed to use SAS (side angle side).

See the diagram below. In the diagram, angle BCD (green) is between segments BC and CD. Also, angle JCD (blue) is between JC and CD.
