Step-by-step explanation:
400 meters is standard lap distance for a race track. 2 x 50 meters is lap distance in International pools. A lap of 440 yards is 1/4 mile. So 4 laps/mile.
The values of x are -22 and -2 and there are not extraneous solutions
<h3>How to solve the equation?</h3>
The equation is given as:
2|x + 7|= x - 8
Expand the absolute bracket
|2x + 14|= x - 8
Remove the absolute bracket
2x + 14 = x - 8 and 2x + 14 = -x + 8
Evaluate the like terms
x = -22 and 3x = -6
This gives
x = -22 and x = -2
Hence, the values of x are -22 and -2 and there are not extraneous solutions

Answer:
2x+4y=22
-2x+2y=+8
6y=30
y=5
now
replace the value of y in equ i
2x +4y =22
2x+20=22
x=1
Area of a Rectangle = Length x Width
28 ft² = L x 5ft
28 ft² / 5ft = Length
5.6 ft = length. CHOICE A.
Perimeter of a Rectangle = 2(L + W)
20 ft = 2(L + 4)
20 ft = 2L + 8
20 - 8 = 2L
12 = 2L
12/2 = 2L/2
6 ft= Length CHOICE A.
