-3/4 or it could also be -0.75
Answer:
x = 
Step-by-step explanation:
Let the number be x
x + 2x² = 10
Factorize x + 2x²
x(1 + 2x) = 10
Divide both sides by (1 + 2x)
x = 
' n ' the 'n'th term
1 4
2 2
3 0
4 -2 .
In general, the 'n'th term of the sequence is A(n) = 6 - 2n .
12x > 18x - 27 - 15
12x > 18x - 42
12x - 18x > -42
-6x > -42
x < -42/-6
two negatives make a positive so now its x < 42/6
Lastly divide 42/6 so it can equal 7
Answer: X < 7.
The answer is 648.
You have to multiply 36 by 18 to get 648
36×18 = 648
Hope that Helps :]
