Answer:
8
Step-by-step explanation:
28-12=16
16/2=8
Simple!
So you can’t factor out the variables since one is d and the other is a. If they were the same letter you could factor them out as well
The only number that goes into both 9 and 12 is three
So divide by three essentially and take it out and place is next to the rest of the equation that is now in parenthesis
3(3d^3 - 4a^2)
As shadow is directly propotional to height, we can say that,
Height/Shadow =k, where k is a constant.
So, in case of electric pole,
1410=k→(1)
In case of tree,
HT15=k→(2), where HT is height of tree
So, from (1) and (2),
1410=HT15
HT=14∗1510=21m
So, height of tree is 21 meters.
hope it helps thank youuuu
