Answer:
39
Step-by-step explanation:
Alll the sides equal each other because of that curve u see at each angle, that curve means that the angles are the same, having the same angles means same sides, so just pick two equations to do this:
21 - x = 2x -3
add 3 to both sides
24 - x = 2x
add x to both sides
24 = 3x
divide by 3
8 = x
Now input 7 into the equations:
21 - x = 21 - 8 = 13
2(8) - 3 = 16 - 3 = 13
x + 5 = 8 + 5 = 13
Now add: 13 + 13 + 13 = 26 + 13 = 39
Another way for u to save time is remember how i said all the sides were the same? you could just solve one equation, so it'll be 13 and multiply that with 3 to get the perimeter since ur adding 13 three times anyway
So just a simple: 13(3) = 39

Answer:
The answer to your question is F = 110.4 N
Step-by-step explanation:
Data
mass = 92 kg
acceleration = 1.2 m/s²
Force = ?
Process
To solve this problem use Newton's second law which states that the acceleration of an object is dependent upon two variables, the net force acting upon the body and the mass of the object.
Formula
F = ma
-Substitution
F = (92)(1.2)
-Result
F = 110.4 N
