The perimeter of a triangle is 14x - 4. If two of the sides measure 3x - 2 and 5x + 3, then how
long is the third side?

14x-4 - (3x-2) - (5x+3) =

14x - 4 - 3x + 2 -5x - 3 =

6x - 5

check let x=1. Then the perimeter is 10 and

the 2 sides are 1 and 8. That leaves 1 for the

3rd side and 6(1)-5 = 1, so it checks.

Step-by-step explanation:

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
