Distribute the -3 to both 2n and 1 (inside the parenthesis)

-3 x 2n = -6n
-3 x 1 = -3

-6n - 3 + 7 = 5

simplify

-6n + 4 = 5

isolate the n

-6n + 4 (-4) = 5 (-4)

-6n = 1

-6n(/-6) = 1(/-6)

n = -1/6

hope this helps

A rug is shaped like a rectangle whose perimeter is 276276 ftft. the length is 5 times as long as5 times as long as the width. f

ArbitrLikvidat [17]

Width = w

Length = 5w

Given,

Perimeter = 276 ft

5w * w = 276

w² = 55.2

--- w = 7.429670248402684 ≈ 7.43 ft

--- l = 5w = 5*7.43 = <span>37.14835124201342 </span>≈ 37.15 ft

Answer:

r = 6.4/(1+sin(θ))

Step-by-step explanation:

As the attachment shows, for the given directrix and eccentricity, the equation is ...

$r=\dfrac{ed}{1+e\sin{\theta}}\\\\r=\dfrac{1.6\cdot 4}{1+1.6\sin{\theta}}\\\\\boxed{r=\dfrac{6.4}{1+\sin{\theta}}}\qquad\text{matches the 2$^{\text{nd}}$ choice}$
