Answer:
x=2
x=-5
Step-by-step explanation:
You need to get everything on one side to have a quadratic equation:
x^2+6x-4 -(3x+6) = x^2+3x-10
All factors of 10 are 1*10 and 2*5.
5-2 = 3 and 5*-2 = -10
Factoring x^2+3x-10 gives us (x-2)(x+5)
x=2
x=-5

What is the future value of an ordinary?
An ordinary annuity is the one where the monthly deposit occurs at the end of each month rather than at the beginning of the months such its future value based on 5.5% annual interest rate can be determined thus:
FV=PMT*(1+r)^N-1/r
FV=balance in dollars and cents in Yolanda's account at the end of 4 years=unknown
PMT=monthly deposit=$100
r=monthly interest rate=5.5%/12=0.00458333333333333
N=number of monthly deposits in 4 years=4*12=48
FV=$100*(1+0.00458333333333333)^48-1/0.00458333333333333
FV=$5,355.29
