Answer:
the fourth answer
Step-by-step explanation:
this is because 6 x 10 is 60, and is you multiply the height by 3 it gives you 3(6) x 10 which can also be written as 18 x 10 which is equal to 180
divide 180 by 60 which will give you 3, this shows you that the growth from the original area to the new area is 3 times, so the ratio is 3:1
The mean would be 58!! Basically what you’re doing to get the mean is adding all of the numbers together and dividing by how many you’re adding. In this case, you would add all of the numbers and divide by 8 because you have 8 numbers ! :D
30,000 x 0.20 = $6,000 least amount
30,000 +35,000 = 65,000
65000 x 0.20 = $13,000 greatest amount
Answer:
7x² - 6x + 4
Step-by-step explanation:
(4x² - x + 6) - (-3x² + 5x + 2)
4x² - x + 6 + 3x² - 5x - 2
4x² + 3x² - x - 5x + 6 - 2
7x² - 6x + 4
