Correct answer: <span>Dot-and-cross-diagram
</span>

Dot-and-cross diagrams are used to represent covalent bonds. The shared electron from one atom is shown as a dot, while the shared electron from the other atom is shown as a cross.

When drawing dot-and-cross diagrams for covalent bonds, you only need to show the electrons in the highest occupied energy level, as only these are involved.

The drawing is composed of a rectangle and a semicircle. Find the area of the figure to the nearest unit. Please explain, thank
DanielleElmas [232]
We know that
[area of the figure]=[area of rectangle]+[area of semi circle]

area of rectangle=b*h------> 10*18-----> 180 cm²

area of semicircle=pi*r²/2
diameter=18 cm
radius=18/2----> 9 cm
area of semicircle=pi*9²/2-----> 127.17 cm²

[area of the figure]=[180]+[127.17]------> 307.17 cm²
round <span>to the nearest unit </span>------> 307 cm²

the answer is
the area of the figure is 307 cm²

Simplify completely quantity 6 x minus 12 over 10.
Natali [406]
Hey! 
So we have 6 multiplied by -12 and that is over 10
so we are multiplying a positive number by a negative number. When you do that the answer will be a negative number. 
Now we have -72/10
we can simplify that more
divide the numerator and denominator by 2 because that is the largest number that is divisible by both number
now it is -36/5
The answer is -36/5
Hope this helps!
