Hi!
To solve this, let's divide
625/250 = 2.5
So is the pattern.. x/2.5 = x2/2.5 = x3/2.5...
We can test this theory by multiplying
100 x 2.5 = 250
Since 250 comes before 100 in the sequence then our theory is correct!
So to find the next numbers, divide:
40/2.5 = 16
16/2.5 = 6.4
6.4 = 2.56
The answer is C.
Hope this helps! :)
Answer:
D.) 75 meters
Step-by-step explanation:
1 minute is 60 seconds
So, you divide 60 divided by 40=1.5
1.5 times 50=75
75 meters
D.)
Hope this helped!! :)

Step-by-step explanation:
Answer:
x = (1/2) (-9 ± √73)
Step-by-step explanation:
Using completing the square method
x²+9x+2=0
x²+9x = -2 (complete the square by adding (9/2)² to both sides)
x²+9x + (9/2)² = -2 + (9/2)²
( x + (9/2) )² = -2+ (9/2)²
( x + (9/2) )² = -2+ (81/4)
( x + (9/2) )² = 73/4
x + (9/2) = ± √(73/4)
x + (9/2) = ± √(73) / 2
x = -(9/2) ± √(73) / 2 (factorize out (1/2) )
x = (1/2) (-9 ± √73)
