We can use t=x^2 to solve this
Once we do that we will have simple square equation which we know how to solve.
t^2 + 3t + 2 = 0
t1 = -1
t2 = -2
x1 = √-1 = i
x2 = -i
x3 = √-2 = i√2
x4 = -i√2
Make sure you know that i^2 = -1 and (-i)^2 = -1 which gives us solutions we got...
Answer: 60%
Step-by-step explanation: 24/40 = .6 x 100 = 60
Your answer is 0.6. I hope this helps.
So, on day 1, the plant was say "P" cm tall.
then 2 weeks go by, or 14 days, and the plant grew to 452 cm.
We are given to understand as per the problem that one must save 10% of their take home pay.
Reggie's take home pay is $2,340 per month
As per the rule Reggie must save 10% of 2,340 per month = 0.10*2,340 = $234 per month
Since we need to know the savings in a year, we have to multiply the monthly savings by 12 since there are 12 months a year
Minimum amount per year that he should save = $234 *12 = $2,808
Minimum amount per year that he should save = $2,808
