Answer:
a. (x^3+8)(x^2-4)
b. x=1 and x=1/2
Step-by-step explanation:
a. (x^3+8)(x^2-4) = x^5-4x^3+8x^2-32 [foil method: first,outside,inside,last]
b. use quadratic formula: -b +/- square root b^2-4ac / 2a
2=a; -3=b; 1=c
-(-3) + square root (-3)^2 - 4(2)(1) / 2(2)
3 + 1 / 4 = 4/4 = 1
3 - 1/4 = 2/4 = 1/2
18-4.25=13.75 the original minus what she already spent
13.75-9.75=4 that minus what she has to save
.50x=4 where x=the number of packages
divide both sides by .50
x=8 Fiona can buy 8 packages of crackers
Hope that helps.
