Answer:
16 bottles
Step-by-step explanation:
you can buy 16 bottles
$709.21
$361.36 for week one + $347.85 for week two = $709.21 total for both weeks
We know that
in the figure <span>equivalent ratios are
</span>BS/BC
and
AR/AC
therefore
AR/RC is not equivalent
the answer is
AR/RC
The only way to solve if it is equal to something
assuming that the teacher wanted you to make it equal to zero do
0=-3x^2-21x-54
remember if we can do
xy=0 then assume x and y=0
so factor
0=-3x^2-21x-54
undistribute the -3
0=-3(x^2+7x+18)
remember 0 times anything=0 so
x^2+7x+18 must equal zero
use quadratice formula which is
if you have
ax^2+bx+c=0 then
x=

x^2+7x+18
a=1
b=7
c=18
x=

x=

x=

i=√-1
x=

the zerose would be
x=

or
