Factor:
9x^2 - 64
= (3x)^2 - 8^2
= (3x + 8)(3x - 8)
If you want to solve it, let the equation equal zero
(3x + 8)(3x - 8) = 0
3x + 8 = 0 ; x = -8/3
3x - 8 = 0 ; x = 8/3
Solutions: x = -8/3 and x = 8/3
I think $-57million. I added them
Answer:
110 i think
just search 12% of 125 the subtract it from 125
A = P(1 + rt)
solve for t
t = ((A/P)-1)/r = ((10000/8000)-1)/0.06 = 4.167 years
