<h3>Answer: 2x+10 inches</h3>

Explanation:

There are 2 opposite sides that are x inches long, so they add to x+x = 2x

Then there are 2 opposite sides that are 5 inches long, which add to 5+5 = 10

Overall, the four sides add to 2x+10 inches

You could also apply the formula below

P = 2L+2W

P = 2x+2*5

P = 2x+10

That formula is the same as P = 2(L+W)

tanya will and juan are playing a game online, juan scores 101,473 points tanya scores 9,879 fewer points than juan and will sco

jekas [21]

Since we know that Tanya scored 9,879 fewer points than Juan, we have to subtract 101,473 from 9,879.

101,473-9,879=91,954.

91,954 represents Tanya's points. Now, we'd have to add that to 9,835 points because Will scored more than her.

91,954+9,835=101,429.

Will scored 101,429 points in this game.
