The perimeter of the trapezoid shown is 6x+2 units. find the length of the missing side

x + 1

Step-by-step explanation:

Is that a lone x on the left hand side? I will assume so.

Let y be the value of the side marked with a ?.

x + 3x + 1 + x + y = 6x + 2     collect the like terms on the left.

5x + 1 + y= 6x + 2                  Subtract 1 from both sides.

5x + 1-1 +y = 6x + 2-1             Combine

5x + y = 6x + 1                        Subtract 5x from both sides.

5x-5x + y = 6x -5x +1             Combine

y =x + 1

The missing side is x +1

answer is

c) 4

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.
