Answer:
Length of the room is 180 ft
Step-by-step explanation:
We have a rectangular room with dimensions:
width = 70 ft and length "x" (unknown)
Perimeter of a rectangle is 2*w + 2*x and according to problem statement 500 ft of lights will fit exactly in room perimeter then:
2*70 + 2*x = 500
140 + 2*x = 500
2*x = 500 - 140
2*x = 360
x = 360/2
x = 180 ft
4:2 can represented as 4 / 2. Or also 2.
30 / 2 = 15
1+3^2=3^2 which is 3(3), and that equals 9. 9/5= 1.8.
1.8-6=-4.2
-4.2+2= -2.2
14(20x) > 2(174.38) note that the greater than should really be a greater than or equal to symbol, I just don't have it on my keyboard.
