<u>Answer:</u>
Limit = -1
<u>Step-by-step explanation:</u>
We are given the following function:

We are to calculate the limit of this function as x approaches zero.
For that, we will use direct substitution method and substitute the x with 0 in the given function to calculate its limit as follows:


Therefore, the limit is -1.
Answer:
base = b = 5
height = h = 13
Step-by-step explanation:
Given Data:
Area of Parallelogram = A = 65 
base = b = x -4
height = h = x+4
Formula:
A = b×h
Solution:
A = b×h
65 = (x-4)×(x+4)
65 =
∴ (a-b)(a+b) = 
65 = 
= 65 + 16
= 81



Now,
base = b = x -4 = 9-4
base = b = 5
height = h = x+4 = 9+4
height = h = 13
Answer:
50%
Step-by-step explanation:
increase = 120 - 80 = 40 which is 50 % of 80
