Isabella typed 12 pages of a book each day. She finished typing the book in 15 days. The book had 4 chapters. Each chapter of the book had the same number of pages. How many pages were there in each chapter of Isabella’s book?

45

Step-by-step explanation:

15 x 12 = 180

180 divided by 4 = 45

45 x 4 = 180

(if correct plz mark brainliest)

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
