Step-by-step explanation:
|...| means absolute value of "...". that means always the "+" value of "...", even if it is negative.
in other words
|-x| = x
|x| = x
|-x - 2y| for x = -2 and y = 3
|- -2 - 2×3| = |2 - 6| = |-4| = 4
Step-by-step explanation:
To find quadrilateral's you need to find shapes with edges.

I'm assuming that you meant to write 'two 100-w per hour light bulbs used a total of 400w. how many hours did the bulbs run'
so each used 100w per hour and there are 2 light bulbs so in 1 hour 200w is used
200wh times x hour=200wx=400w
divide both sides by 200w
x=2
they ran for 2 hours

Step-by-step explanation:
Answer: Area of cross section would be 4 square units.
Step-by-step explanation:
Since we have given that
Area of base of cone = 16 sq. units
Height = 10
We need to find the area of cross section that is distance 5 from the vertex.
So, Height of cross section = 5 units
total height of cone = 10
It means the cross section is half of the whole cone.
So, it becomes,

Hence, Area of cross section would be 4 square units.
