Answer:
Theyre both going to be 27.
Step-by-step explanation:
2n+21=4n+15
-2n -2n
21=2n+15
-15 -15
=
3=n
2n+21
2(3)+21=27
4n+15
4(3)+15=27

Answer:
Step-by-step explanation:
1. 2 + 3{(4 - 1)2}
let solve the bracket first
2+3{(3)2}
2+3(9)
2 + 27
=29
2. 3y - ( x +2)
where x = -5 and y = 3
3(3) - (-5 + 2)
9 + 5 - 2
i multiply the bracket with negative sign
9 + 3
= 12
3. 2(4x - 3) + 3x
distribute
8x - 6 + 3x
combine the like terms
8x + 3x -6

Step-by-step explanation:
The distance between the boat and the ocean's floor is 19m
<h3>
How to get the distance from the ship to the ocean's floor?</h3>
We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.
We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).
Then we use the relation:
Sin(a) = (opposite cathetus)/(hypotenuse).
Replacing the values that we know, we get:
Sin(39°) = d/30m
sin(39°)*30m = d = 18.9m ≈ 19m
The distance between the boat and the ocean's floor is 19m.
