Answer:

12a^3 + 2a^2 + 23a + 18    

Step-by-step explanation:

Please use the " ^ " symbol to represent exponentiation:   4a^2 – 2a + 9.

Now carry out the multiplication as follows:

First, multiply each term in 4a^2 – 2a + 9 by 3a:  12a^3 - 6a^2 + 27a.

Next, multiply each term in 4a^2 – 2a + 9 by 2:  8a^ 2 - 4a + 18.

Now combine like terms:

12a^3 - 6a^2 + 27a

            8a^ 2 - 4a + 18

---------------------------------

12a^3 + 2a^2 + 23a + 18

The ant Fidencia found a leaf, the charge and took the anthill. She gave her friend 1/5 and she ate 1/3 of the leaf. Who ate more?

Her friend

(1/5)*(3/3)=3/15

Ant Fidencia

Multiply (1/3) by (5/5)

(1/3)*(5/5)=5/15

Compare

5/15 > 3/15 -----> two fractions with the same denominator the fraction with the highest numerator is greater

The distance the water is traveling and the time it took.
