Answer:

3 (4 x + 6): Each side length is 4 x + 6 units.

I think that is the right answer?

Answer:

So each side length is 4s+6

Step-by-step explanation:

Since we know the triangle is an equilateral triangle, we know the perimeter of the triangle is given by since all the sides are the same length

P = 3s  where s is the side length

12x+18 = 3s

Divide each side by 3

12x/3 + 18/3 = 3s/3

4s +6 = s

So each side length is 4s+6

k0ka [10]

Answer:

B. 41.8° is the correct answer

Step-by-step explanation:

We are given that,

Length of Eduardo's flight path = 273 miles

Length of Paul's flight path = 357 miles

Distance between their destinations = 238 miles.

Now, using the law of cosines, we get,

238^2=273^2+357^2-2\times 273\times 357\times \cos \theta

i.e. 56644=74529+127449-194922\times \cos \theta

i.e. 56644=201978-194922\times \cos \theta

i.e. 194922\times \cos \theta=145334

i.e. \cos \theta=0.7456

i.e. \theta=\arccos 0.7456

i.e.  θ = 41.8°

Hence, the angle between their flight paths is 41.8°.

33-7r = 3(6-4r) what does r equal?
dlinn [17]
33-7r = 3(6-4r)
33 - 7r = 18 - 12r
33 -7r + 7r = 18 - 12r + 7r
33 = 18 - 5r
33 - 18 = 18 - 5r - 18
15/5 = 5r/5
3 = r
r = 3
