Use quadratic formula since we can't factor
for 0=ax²+bx+c

so, for
0=1x²-6x-4
a=1
b=-6
c=-4





the solutions are x=3+√13 and x=3-√13
or aprox
x≈6.61 and x≈-0.61
Answer: 7 blocks west
Step-by-step explanation:
she goes 8 blocks south
13 blocks west
8 blocks north
and 6 blocks east.
the 8 blocks south and then north cancel each other out, so she is on the same street horizontally, but the 13 blocks west only get 6 blocks back east, so she ends up 7 blocks west of her starting point because 13 - 6 = 7
The answer=24 that he needs to put in each pile
A=p(1+r)^t
A=650×(1+0.08)^(14)
A=1,909.18
Interest earned=a-p=1909.18-650=1,259.18
