80

That's the answer

Step-by-step explanation:

No explanation

80 meters

Step-by-step explanation:

There are two ways you could do this.

1st way (my personal way of doing it): Add 25 + 15 + 25 + 15. Then subtract that by 9 + 7 + 9 + 7 (you do this because that will find the perimeter of the open space.)

=> 25 + 15 + 25 + 15 = 80

=> 9 + 7 + 9 + 7 = 32

=> 80 - 32 = 48

2nd way: Add 25, 15, 16 and 8. (You are adding the sides that they already give you.) Then, you would find the missing sides (or the sides that don’t have a number on the .) And that would be 7 and 9. So you add the sum of those two numbers to your answer.

=> 25 + 15 + 16 + 8 = 64

=> 7 + 9 = 16

=> 64 + 16 = 80

This might be very confusing but I hope this helps :’)

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
