Answer:
Just do your best
Step-by-step explanation:
Width=x
length=3x
perimeter=2*(x+3x)=8x
8x=120
x=120/8=15
therefore width is 15cm
all the best, and thnx for this question

Step-by-step explanation:
The ceiling of numbers between -1 and 0 (not including -1) will be 0. Adding 3 to that moves the segment up to y = 3. Hence, the last graph is the appropriate one.
Any integer is its own ceiling, and it is also the ceiling of numbers between that and the next lower integer. Hence each segment on the graph will have an open circle at the left end and a closed circle at the right end.
The given function is:
x^2 - 1
We want to calculate the limit of this function as x approaches zero. To do so, we will use direct substitution.
We will substitute the x with 0 in the given function to calculate its limit as follows:
Limit as x approaches 0 = (x)^2 - 1 = -1
Therefore, the correct choice is:
-1
