To find the area of a triangle do base times height and divide that by two. So you would do the bottom line and the side line and multiply that and divide the total in half.
17×2= 34
76-34= 40
2x=40
x= 20
Legth: 17
Width: 20
Ok, find change then divide by years elapsed
change=310-280 million=30 million
number of years elapsed=10
30mil/10=3mil
3million per year was the population growth rate
Answer:

Step-by-step explanation:
2p + 3r = q
2p + 3r - 3r = q - 3r [ subtract 3r from both sides ]
2p + 0 = q - 3r [ -3r + 3r = 0 ]
2p = q - 3r
[ divide by 2 on both sides ]
