<h3>
Therefore 45.87 m from which the object was dropped.</h3>
Step-by-step explanation:
Given , the velocity of free fall object is given by
where v is the velocity (m/s) g is acceleration due to gravity (m/s²) and h is the the distance (m) fallen.
v = 30 m/s
g = 9.81 m/s²

⇔v² = 2gh [ squaring both sides]



Therefore 45.87 m from which the object was dropped.
First, you do the distributive property on:
4(2n+3)
You would get
8n+12
Then add the original part of the equation in (4n)
4n+8n+12
Combine like terms
12n+12 is the answer
Top triangle area: 7×8 /2 -> 56/2= 28
right triangle area: 6×5 /2 -> 30/2= 15
rectangle area: 5×8 -> 40
40+28+15
68+15
