Answer:
(Frequency of the value being measured divided by the total frequency) times by 100
I think the answer is c 90 percent chance
7a^3(6a^2 + a)^2 - 4a^6
All we have to do here is basically add and subtract exponents!
(6a^2 + a)^2 = 36a^4 + a^2
7a^3(36a^4 + a^2) - 4a^6
252a^7 + 7a^5 - 4a^6
Answer is C.
1,2,3,5,6,10,15,30 because by looking at the number at the ones place, when it is 0 or an odd number, it could be divided by 2. When the places are added together and when it is divisible by 3, it is the factor of 3. Also, when there are 2 and 3 as a factor, it is also divisible by 6.
