Answer:
C) 2(4x² + 5x - 4) is your answer
Step-by-step explanation:
Factor out common factors from all terms.
Note the factors for 8 & 10:
8: 1, 2, 4, 8
10: 1, 2, 5, 10
2 is the largest common factor, and so factor out 2
8x² + 10x - 8 = 2(4x² + 5x - 4)
C) 2(4x² + 5x - 4) is your answer
Note that you cannot factor out anymore common factor numbers or variables.

Answer:
16.42 years
Step-by-step explanation:
Use the Future value formula; FV = PV (1+r)^t
PV= Initial amount deposited, 500
r= interest rate or discount rate, 2.5%
t = total duration of the investment, ?
FV= future value of account, 750
Plug in the numbers into the formula
750 = 500* (1+0.025)^t
divide both sides by 500
750/500 = 1.025^t
put ln on both sides
ln 1.5 = ln
ln 1.5 = t ln 1.025
0.4054651 = 0.0246926 t
Divide both sides by 0.0246926
0.4054651/0.0246926 = t
t = 16.42
16.42 years
Answer:
I believe it is A I might be wrong tho I just learned this stuff today
The simplified ratio would be 8 girls and 9 boys
