Answer:
Step-by-step explanation:
"One number is eight less than a second number."
x = y-8
"Twice the first is 12 more than 4 times the second."
2x = 4y+12
substitution
2(y-8) = 4y + 12
2y - 16 = 4y + 12
2y = -28
y = -14
x = y-8 = -22
Factor w+1 out of 4x(w+1)+5y(w+1).
(w+1)(4x+5y)

Answer:
The correct answer is option C, 228 feet
Step-by-step explanation:
As per Newton’s third law of motion:
V2 – U2 = 2 x a x S
Where V = final velocity
U = Initial Vlocity
a = acceleration (-ve)
S= distance travelled
V= 0 mph
U= 55 mph = 80.6667 ft /sec
0 – (80.6667 ft /sec)2 = 2 x (-g/2) x S
S = (80.6667 ft /sec)2 /(32.2 feet per second per second x0.5)
S = 202.1 feet
So the most nearest option is option C
