Answer:
B
Step-by-step explanation:
i cant explan for this quasion but i am not understand this quation
The first one is the correct answer
Y-7=-3(x+2)
Assume uniformly accelerated motion
Vf = Vo - at => a= [Vo - Vf] / t
Vf = 0, t = 20 s => a = Vo / 20
x = Vot - at^2 / 2
x = Vot - (Vo / 20) * t^2 /2
x = 1775 feet * [1 mile / 5280 feet] = 0.336 mile
t = 20 s
=> 0.336 = 20Vo - Vo(20)^2 /(40) = 20Vo - 10 Vo = 10 Vo
=> Vo = 0.336 /10 = 0.0336 mile /s
Vo = 0.0336 mile/s * 3600 s/h = 120.96 mile / h
Therefore, the car was way over the speed limit.

2 has to be outside the parenthesis, 34 divided by 2: 17, 6 divided by 2: 3
2(17z+3)
W = L - 5
A = W.L
14 = (L - 5).L
14 = L² - 5L
L² - 5L -14 =0
(L - 7)(L + 2) = 0 {factorized}
L = 7 / L = -2
In this case L would be equal to 7 because a length of anything can't be a negative number
Therefore, W = 2
Answer : Length = 7 Width = 2
