<span>If 43% of adults say cashews are their favorite kind of nut, then if you ask 12 adults the result should be: 12 adults x 43%= 5.16 adults.
If you round the result, you will get 5 of 12 adults saying that cashews are their favorite nut. Then the right option would be </span><span>(b) at least four</span>
replace x^2 with m and try to solve
-3 m^2 +27 m +1200 =0
factor out -3
-3(m^2 -9m-400)=0
-3 (m-25) (m+16) =0
using the zero product property
m-25 =0 m+16=0
m=25 m=-16
then substitute m=x^2 back in
x^2 = 25 x^2 = -16
x take the square root of each side
x = +- sqrt (25) if you know complex number x = +- sqrt (-16)
x = +-5 x = +- 4i
Answer: +5, -5 , +4i, -4i
