Answer:
D) 11x + 9
Step-by-step explanation:
3(2x + 5) - (-5x + 4) = (6x + 15) - (-5x + 4) = 6x + 15 + 5x - 4
add like terms:
(6x + 5x) + (15 - 4) = 11x + 9
Each side is twelve feet long. take the perimeter and divide by three to get your answer.
12+2+8+6+57=85
85/5= 17
mean=17
you would use 1.5 packets, but that requires 2 packets.
1 packet in total would feed 8 people, and half of another would feed an extra 4. 4+8 = 12.
