Answer:
Step-by-step explanation:
1 ) 2 + 7t [ there are no like terms , so no further simplifying ]
2) 6r + ( - 16 r )
= 6 r - 16 r [ both are like terms ]
= - 10 r
3) (3x + 2 ) + ( 2x - 4 )
= 3x + 2 + 2x - 4
= 3x + 2x - 4 + 2 [ arranging like terms together ]
= 5x - 2
4) (8 n² - 3 n + 6 ) + ( n - 2 )
= 8n² - 3n + 6 + n - 2
= 8n² - 3n + n + 6 - 2 [ bringing like terms together ]
= 8n² - 2n + 4
Answer: 40
Step-by-step explanation:
5 * 8 = 40
The first one is none of above, it is vertical opposite angles.
the second to the left is also none of above, since the 2 lines are not parallel to each other.
the third one in the right is corresponding
the fourth one is alternative exterior
the last one is none of above because again the lines aren't parallel
The answer is 9300
Hope this helped :)

You would add the total number sandwiches together and divide by the total number of platters.
