x2 - 12x = -6
Your next step would be to add 36 to both sides.
x2 - 12x + 36 = 30
In completing the square, we divide the term before x by 2, and then square it and add it to both sides.
12 / 2 = 6
6^2 = 36
That would be the next step.
Answer:
Least: -s
Greatest: s
closest to 0: s+r
Step-by-step explanatio :
It's kind of obvious that the smallest value is going to equal -s which means that the largest is s which leaves s+r to be the value that's cloest to 0
What does one poop say to the other ?
Answer:
- sugar cookies -- $4
- oatmeal cookies -- $8
Step-by-step explanation:
Using "s" and "o" to represent the prices of packs of sugar and oatmeal cookies, respectively, we can write the revenue equations as ...
10s +2o = 56
9s +3o = 60
In standard form (with common factors removed), these equations are ...
5s + o = 28
3s + o = 20
Subtracting the second equation from the first, we find ...
(5s +o) -(3s +o) = (28) -(20)
2s = 8 . . . . simplify
s = 4
Substituting into the first equation, we have ...
5·4 +o = 28
o = 8 . . . . . . subtract 20
The price of a pack of sugar cookies is $4; of oatmeal cookies, $8.
