2x+8+ 120= 180
Combine like terms so 8+120=128
2x+8+ 120= 180
2x+128=180
-128=-128 ( to both side)
2x= 52 You divide now
2x/2= 52/2
x= 26
There is your answer :)

Step-by-step explanation:
Total population = 1000 snails
AA = 160 snails
Aa = 480 snails
aa = 360 snails
Frequency of each type.



Now, we get

he frequency of the A allele in this population is 0.4.
Therefore, the correct option is C.
one of those questions are polynomials and the one that is a polynomial is obviously the answer and that would be the third one
