Answer:
The answer for x is 14
Step-by-step explanation:
The value of x is 72
Each side increased by 20%
Answer:
x=16
Step-by-step explanation:
60=5x-20
60(+20)=5x
80/5=x
16=x
The answer is 280 because you multiply 7cm x 2cm , then 2cm x 14cm, then you multiply is 14cm x 7cm . Then 7x2=14 , 2x14=18 ,then 14x7=98. So multiply 28,96, and 14 by 2 to get 196 ,56, and 28. Then your total will come up to 280
In order to be differentiable everywhere, must first be continuous everywhere, which means the limits from either side as must be the same and equal to . By definition, , and
so we need to have .
For to be differentiable at , the derivative needs to be continuous at , i.e.
We then need to have
Then
