Answer:
n = -9
Step-by-step explanation:-
Answer: 
Step-by-step explanation:
The missing figure is attached.
The perimeter of a rectangle is:

Where "l" is the lenght and "w" is the width.
You can identify in the figure that:

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

Now you must simplify and solve for "z"

Finally, substituting the value of "z" into
, you get:

Answer:
-33
it just adding -3
ex: -6+-3= -9
hope this helped
-18 is the fifth one add -3 and its -21 which is the 6th one. then you keep going and get -33.
Answer:
f(-2.75)=-1
Step-by-step explanation:
Here we are given a Greatest Integer Function . The characteristic of this function is that it when operated , gives you the greatest integer it has near to it.
Hence if we have any greatest integer function f(x)=[x] , for x = -2.75
[-2.75]=-2 , as -the greatest integer near to -2.75 is -2 as -3<-2
Now coming back to our problem, our function is
f(x)=[x]+1
Hence for x=-2.75
f(x)=[-2.75]+1
as we discussed above [-2.75]=-2
Hence
f(-2.75)=-2+1
f(-2.75)=-1
It’s should be 30 if the triangle is drawn to scale
It would absolutely not be 180 because that’s the sum of all angles of the triangle
It could be 75 but if the triangle is drawn to scale then the two isosceles angle should be greater than angle U, so it won’t be reasonable if angle U is 75
