The height of the tree was 56 inches.
We can calculate the percentage of a certain amount by :
Subtracting New - Original / New multiplied by 100
this implies it will be
75 - x / 75 × 100 = 25 %
7500 - 100 x = 1875
this implies 7500 - 1875 = 100 x
5625 = 100 x
Thus , On dividing both sides by 100 we get
56.25 = x
Now on rounding off this number we will get
56 = x
Thus the original height of the corn plant was 56 inches

The GCF is 7 which will give you 7(4n+6n)
explanation: 7 goes into 28 times and 7 goes into 42 6 times. and
To determine if a number is divisible by 7, take the last digit off the number, double it and subtract the doubled number from the remaining number. If the result is evenly divisible by 7 (e.g. 14, 7, 0, -7, etc.), then the number is divisible by seven.
Answer: Choice B
======================================================
Explanation:
The original equation is 
with 8 as the base. That is also the base of the log when we get the final answer shown above. Logs are useful to isolate the exponent.
The general rule is that 
is equivalent to the log form of 
where b is the base of each.
