7x-c=k
7x-c+c=k+c
7x=k+c
7x/7=(k+c)/7
x=(k+c)/7
Using pythagorean theorem. We know the hypotenuse will be 20, c. Either a or b could be 18 is doesn’t matter.
18^2+b^2=20^2
324+b^2=400
-324
b^2=76
Square root 76
You should put the later 2 square roots of 19 away. or 8.72 feet away
Answer:

16/25
3/4
5/6
Step-by-step explanation:
Convert them to decimals then order them
Answer:
For maximum area, all of the wire should be used to construct the square.
The minimum total area is obtained when length of the wire is 10m
Step-by-step explanation:
For maximum, we use the whole length
For minimum,
supposed the x length was used for the square,
the length of the side of the square = x/4m
Area =
For the equilateral triangle, the length of the side = 
Area = 
Total Area =
+ 

, therefore it is minimum


x = 10.00m
Reciprocal is basically just swapping them around, so for 10/3 it's 3/10 and that's your answer!
