The sum of their ages equals 80.
Gabrielle is 3 times older than Mikhail
Two numbers that have a sum of 80, with one number being 3 times the other are:
Gabrielle’s age: 60
Mikhail’s age: 20
60 + 20 = 80
20 x 3 = 60
Mikhail is 20 years old.
19.4 divided by 2, to find the radius. Then square it, and then multiply it by pi. Which gives you A as the answer
The polynomial
arranged in descending order is 
Step-by-step explanation:
We need to rewrite the polynomial
in descending order.
For writing the polynomial in descending order we arrange the exponents of variables from largest exponent to the smallest exponent.
The given polynomial is:

The descending order of the polynomial is:

So, the polynomial
arranged in descending order is
