Answer:
176.58 m/s
Step-by-step explanation:
assume that the acceleration due to gravity, g = 9.81 m/s²
I also assume we neglect air resistance (hence we assume no terminal velocity)
recall that one of the equations of motions can be expressed as
v = u + at, where
u = initial velocity = 0 (because it says you started from rest)
v = final velocity (we are asked to find this)
a = acceleration due to gravity = 9.81 m/s²
t = time = given as 18s
simply substitute the above into the equation.
v = 0 + (9.81)(18)
v = 176.58 m/s
The solution to this puzzle is 10+3 = 13
<h3>How to solve the puzzle</h3>
To solve this the values at the top of the star were gotten by the addition of two values inside the stars.
- 3 + 12 = 15
- 12 + 4 = 16
- 4 + 2 = 6
- 2 + 10 = 12
- 10 + 3 = 13
Therefore the answer to this question is 13.
Another way of getting the value is by adding 15 + 16 = 31
12 + 6 = 18
31-18 = 13

Answer:
11 and 51
Step-by-step explanation:
1 technically isn't a prime since a prime can only be divided by two things (itself and 1) and 1 can only be divided by 1.
21 can be divided by 1, 3, 7, and 21 so it is not prime.
Hope this helps!
Answer:
20x^2+23x+6
Step-by-step explanation:
(4x+3)(5x+2)
(4x)(5x)+2(4x)+(5x)3+3(2)
20x^2+8x+15x+6
20x^2+23x+6
Hope that helps :)
