I think it will be 8 1/3 inches. 
(7,7) and (7,3) are 4 units apart
   <u> 7-3</u>  = <u>4</u>
    7-7  = 0
(7,3) and (10,3) are 3 units away
  3-3 = 0; 10-7 = 3
(7,7) and (10,3) are 4/3 units away or 1 and 1/3
  <u>7-3</u> =  <u>4</u> 
 7-10 =-3
  Then, take the absolute value because you can't have negative inches of lace, you get 4/3 or 1 1/3. 
Add them all together for perimiter: 
 4+3+1 1/3 = 8 1/3 inches of lace

Hope this helps!

I need to know how to solve these
My name is Ann [436]
1. make an equation
4x+7(20) = 5(x+20)
2. multiply the numbers and distribute 5 through the parenthesis
4x+140 = 5x+100
3. move variables to the left side and change its sign and move constant to the right side and change its sign
4x-5x = 100-140
4. collect the like terms and calculate the difference
-x = -40
5. change the signs on both sides of the equation
x = 40

9. Five times a number is the same as the number added to five. What is the<br> number?
Alenkinab [10]
Let x be the number

5x = x + 5

subtract x from both sides

5x - x = 5

4x = 5

Divide both sides by 4

4x/4 = 5/4

x = 5/4

=======

Check:

5 * (5/4) = (5/4) + 5

25/4 = 1.25 + 5

6.25 = 6.25





Hope it helps . Note that I am a sixth grade student and I don’t know anything . I got help from somebody
