The half-life of the radioactive element unobtanium dash 31unobtanium-31 is 55 seconds. if 8080 grams of unobtanium dash 31unobtanium-31 are initially present, how many grams are present after 55 seconds? 1010 seconds? 1515 seconds? 2020 seconds? 2525 seconds?

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
