3/5 of jull's 30-page photo album is full. she wants to set aside 1/4 of the pages that are left for photos of her vacation. how many pages can she fill before her vacation?

so her album is 30 pages in total, and we know the 3/5 of that are already in use by photos, how much is 3/5 of 30?  well, is just their product, namely 18.

since 18 pages are already in use, the leftover is 12 pages, now she wants to set aside 1/4 of those 12 for her vacation,  how much is 1/4 of 12?  well, is just their product, namely 3.

how many pages are leftover for her photos of her cat and her dog? well 12 - 3 = 9.

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
