I don’t understand either
Answer :-
<h3>
3 years</h3>
step by step explanation:-
Let the time be x
principal = rs 8000
Amount = rs 13824
rate = 20% p.a
A = P(1+r/100)^n
13824 = 8000 ( 1 + 20/100)^n
=> 13824/8000 = (120/100)^n
=> 13824/8000 = (24/20)^n
=> (24/20)³ = (24/20)^n
=> 3 = n
=> n = 3 years
Answer:
-7
Step-by-step explanation:
To find the common difference, take the second term and subtract the first term
-2 - 5 = -7
Check by subtracting the second term from the third term
-9 - (-2) = -9+2 = -7
The common difference is -7
Its 4-6=2 its easy because just keep useing numbers until the become two
We can use FOIL to solve.
(x + 7)(x + 10)
(x * x) + (x * 7) + (7 * x) + (7 * 10)
x² + 7x + 7x + 70
x² + 14x + 70
Best of Luck!
