Answer:
D. a^2 - 6a - 16
Step-by-step explanation:
The product is found using the distributive property.
(a -8)(a +2) = a(a +2) -8(a +2)
= a^2 +2a -8a -16
= a^2 -6a -16 . . . . . matches choice D

Step-by-step explanation:
Based on the ratings system and the summarize() and mean() functions, the code chunk to add is <u>summarize(mean(Rating))</u> and the mean rating is 3.185933.
<h3>How do you find the mean rating?</h3>
To find the mean rating, the complete code should be trimmed_flavors_df %>% summarize(mean(Rating)).
This code would allow you to see the mean rating of your data by combining the summarize() and mean() functions such that you can display summary statistics.
Because of the "mean()" function, the statistic that will be displayed is the mean rating which in this case would be 3.185933.

Answer:
The surface area of the lower rectangle is 20cm x 4cm= 80 square cm
the surface area of the two triangles is 12 square centimetres
the surface area of one of the top rectangular faces is 20×5= 100 square centimetres
the surface area of the other is 20×3= 60 square centimetres
80+12+60+100=252 square centimetres is the surface area of the polyhydron
