Answer:
x=1 +or- √(1)-(-8)/-2
Step-by-step explanation:
-2=-x+x^2-4
-2+4= x^2-x
2=x^2-x
x^2-x-2=0
Quadratic formula
x=-b +or -√b^2-4ac/2a
from the equation
a=1
b=-1
c=-2
Insert the variables into the quadratic formula
We have
x=-(-1) +or- √(-1)^2 - 4*(1)*(-2)/-2*(1)
=1 +or- √1+8/2
=1 +or-√9/2
=1 +or- 3/2
=1+3/2 or 1-3/2
=4/2 or -2/2
x=2 or -1
gcf=2
12-2=4(3-1)
hope this is right!
It would be 315151515/1000000000
count the digits after decimal, divide that by the power of tenth of that
100 - 16 = 84, and 84 divided by 12 is 7. She needs to buy 7 more boxes of granola bars for her students.
