The number of pages in an Algebra book is 99 less than the number of pages in a geometry book. Write and solve an equation to find the number n of pages in the geometry book.

An equation is *629 = n - 99. The geometry book has 728 pages*

Step-by-step explanation: The Algebra book has 99 pages LESS than the geometry book, in other words, the geometry book has 99 pages MORE than the Algebra book. This equation can be used to find the answer. I’m afraid 530 is not the answer.

Hope this helps! :)

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
