Answer:
No, she doesn't have enough varnish for all the floors.
Step-by-step explanation:
Area of the floor, A= 10x6-5x2=50 
Since 5 m^2 required 1 liter of varnish.
So, the amount of varnish required for 1 = 1/5= 0.2 liters.
The amount of varnish required for 50 = 0.2X50=10 liters.
Now, as 1 tin has 2.5 liters of varnish.
So, the total amount of varnish available = 3x2.5=7.5 liters, which is less than the total requirement.
Hence, she doesn't have enough varnish for all the floors.

All vertical or corresponding angles are congruent, aka they equal eachother.
Answer:
I think is F
Step-by-step explanation:
Answer:
y=√x+5 -1
the answer is option C,,
x=-7,y=√-7+5 -1=√-2 -1
we can't find the square root of negative values, therefore it displays as error
x=-6,y=√-6+5-1=√-1 -1
same reason
x=-5,y=√-5+5-1=√0-1=-1
x=-4,y=√-4+5-1=√1-1=0
x=-1,y=√-1+5-1=√4-1=1
x=4,y=√4+5-1=√9-1=2
