Step-by-step explanation:
(x+5)^2 = 2( 5x-3)
x^2+25=10x-6
x^2-10x+25+6= 0
x^2-10x+31=0
a=1, b
F - 3/4 = 5/6
Add 3/4 to both sides to get
F = 5/6 + 3/4 = 19/12
X=-5 is your answer. Hope this helps :)
Use trigonometry.
sinQ = 14/50 = 0.28
-> angle Q = sin^-1(0.28) = approx 16 degrees
-> cosQ = A/H -> cos16 = PQ/50
=> PQ = 50*cos16 = approx 48.06
So yea.
It would most likely take 3-4 hours, maybe even 5.
