0.2 if you mean 2/10 or 2.5 if you mean 10/2
Multiply the number of sizes by the number of toppings. 3 * 4 = 12 different combinations.
Factor the equation into...
(3b+5)(3b+5)=0
Each factor 3b+5=0 so 3b=-5 so b=-5/3
Check:
9(-5/3)^2+30(-5/3)+25=
9(25/9)-50+25=
25-50+25=0
It checks,
So answer is A.-5/3
