Answer:
11/850
Step-by-step explanation:
Total number of cards in a deck = 52
Total number of diamond cards = 13
P(3 diamond cards)
= 13/52 x 12/51 x 11/50
= 11/850
35*2.5 = 87.5. The dragonfly traveled 87.5 miles.
Answer:
P = 2x² + 8x - 30
P = 12 (if x = 3)
Step-by-step explanation:
Perimeter Formula: 2l + 2w
Step 1: Find perimeter
2(2x² - 16) + 2(-x² + 4x + 1)
4x² - 32 - 2x² + 8x + 2
2x² + 8x - 30
Step 2: Plug in x = 3
2(3)² + 8(3) -30
18 + 24 - 30
42 - 30
12
Hi,
x= 20/3
Have a great day!
