(2, 8)
Because you cannot divide by 0, which 2 would do to the bottom.
Given the function f(x)=x^2+5x+5 , to get the zeros we solve using quadratic formula;
x=[-b(+or-) sqrt(b^2-4ac)]/(2a)
from our function;
a=1,b=5, c=5
thus,
x=[-5(+or-)sqrt(5^2-4*1*5)]/(2*1)
x=[-5(+or-)sqrt(25-20)]/2
x=[-5+/-sqrt(5)/2
The answer is option C
1. 20 slices
2. 54 for herself
Hope this helps
Answer:
Give an example from your life experience (outside of school) where it was important to understand fractions. Eg; how many cups of walnuts does she need for five pans of fudge?
