Answer:
5.4772255750516 that's if it is x squared
Student A starts with $100 in the bank and makes $5 a day. Student B starts with $50 and makes $7 a day. Assuming the students save their money, when will they have the same amount of money ?
10 + x is less than or equal to 8
we are given that
3 chickens to lay 32 eggs
now, we can find number of eggs per chicken
number of eggs per chicken= (total eggs)/(total chicken)
so, we get
number of eggs per chicken is

now, we can set up following
1.5 chicken : 1.5 eggs : 1.5 days
3 chickens : 3 eggs : 1.5 days
1 chicken : 1 egg : 1.5 days
Since, changing number of chicken won't affect time
time to lay eggs will always remain same
so,
for 1 chicken to lay
eggs
it takes

Hello:
(poq)(x) = p(q(x))= p(x-3) = 2(x-3)²-4(x-3) = 2(x²-6x+9)-4(x-3)
(poq)(x) = 2x²-12x+18-4x+12
(poq)(x) = 2x²-16x+30... (answer : C )
