Answer:
1) , 2) The value of is 3, 3) The perimeter and the area of the rectangule are 18 feet and 18 square feet, respectively.
Step-by-step explanation:
Let be a rectangle with a length of feet and a width of 3 feet. The area (), measured in square feet, and perimeter (), measured in feet, formulas are, respectively:
(Eq. 1)
(Eq. 2)
1) Now, we assume that , then we reduce the system of linear equation into a sole linear equation:
(Eq. 3)
2) We proceed to solve for :
The value of is 3.
3) Lastly, we obtain the values of the perimeter and area:
The perimeter and the area of the rectangule are 18 feet and 18 square feet, respectively.
Answer:
10/9
Step-by-step explanation:
12/18÷3/5
Simplify

2/3*5/3
Rule: a/b*c/d=ac/bd
2/5*3/3
Simplify
10/3*3
Simplify
10/9 (decimal 1.1...)
Hope this help's :)
-100= -100-17x
0= -17x
x should equal 0
