Answer:
4L-12
Step-by-step explanation:
let's assume the length = L
then the width of the rectangle is L - 6
perimeter = 2× (a+b)
where "a" and "b" are the length and the width of the rectangle.
so perimeter = 2× (L + L - 6)
2 × ( 2L - 6)
4L - 12
The total distance that Dominik will have to walk is the sum of the length of the escalator and the distance that the escalator has traveled. Let t be the time it will take him to reach the top of the escalator. The equation that best models the situation is,
225 ft + (82 ft/min) x t = (106 ft/min) x t
The value of t is 9.375 minutes.
19/6y+17=-21
19/6y=-38
y=-12
Answer:
x = 8
Step-by-step explanation:
alternate-interior angles equal 180°
17x + 14 + 4x - 2 = 180
21x + 12 = 180
21x = 168
x = 8
