Answer:
x = 10.75
Step-by-step explanation:
To find the value of x, we need to know the equation for the perimeter of a rectangle. This equation is:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
We are given P = 84, L = 3x -1 , and W = x. Now we just plug these values in and solve for x.
P = 2L + 2W
84 = 2 ( 3x - 1 ) + 2 ( x )
84 = 6x - 2 + 2x
84 = 8x - 2
86 = 8x
86 / 8 = x
43 / 4 = x
(40 + 3) / 4 = x
10.75 = x
Hence, the value of x = 10.75.
Cheers.

Answer:
774 km
Step-by-step explanation:
Actual distance
1)
4136 mm = 4136/1000 = 4.136 m = 4.14 m
2)
Since 1 yard = 91.44 cm
Hence, 14.7 yard = 14.7*
91.44 = 1,344.168 cm = 1344 cm
3)
342 inches = 9 yards, 1 ft, 6 inches.
