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
X=25 and y=-2 so then y=-40 and x=? you will have to divide and and multiple and the answer will be x=500
Answer:
D
Step-by-step explanation:
Answer: C is the correct answer Lines r and s and lines t and u must be parallel.
Step-by-step explanation: the step by step explanation is the the lines that answer C says are parallel
Lines r and s are crossed by lines t and u to form 16 angles. Clockwise from top left, at the intersection of r and t, the angles are 1, 2, 3, 4; at the intersection of s and t, 5, 6, 7, 8; at the intersection of u and s, 9, 10, 11, 12; at the intersection of u and r, 13, 14, 15, 16.
Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :
Given Points are (1 , 7) and (-4 , -8)
here x₁ = 1 and x₂ = -4 and y₁ = 7 and y₂ = -8
