Step-by-step explanation:
The valence electrons (outer shell electrons) get shared between the first and second element in the compound the purpose is for both the elements to get to the stable state by having the outer shell filled up to 8 electrons. See image.
Answer:
Step-by-step explanation:
x+5=-6
x=-11
(y-3)/2=-5
y-3=-10
y=-7
(-11,-7)
Answer: 31
Step-by-step explanation: To solve this we want to work backward so we know that 6 and w = 37 so we need to do 37-6=w
37-6=31 so 31=W

Answers:
- x = 7
- Area of shaded region = 162 square units
You may need to leave off the "square units" portion.
=============================================
Explanation:
For now, ignore the smaller rectangle and its dimensions. The larger rectangle has sides 3x and x+5, which I'll call the length and width.
L = 3x
W = x+5
The perimeter of any rectangle is P = 2(L+W). Plug in those values of L and W, and also the given perimeter P = 66. Isolate x.
P = 2(L+W)
2(L+W) = P
2(3x+x+5) = 66
2(4x+5) = 66
8x+10 = 66
8x = 66-10
8x = 56
x = 56/8
x = 7
-------------------
Now that we know x, we can find the area of the rectangles.
As you probably can guess, the shaded region is the difference of the two areas.
A = area of larger rectangle
A = (length)*(width)
A = (3x)*(x+5)
A = (3*7)*(7+5)
A = 252
B = area of smaller rectangle
B = (x+3)*(x+2)
B = (7+3)*(7+2)
B = 90
C = area of shaded region
C = A - B
C = 252 - 90
C = 162 square units is the area of the shaded region.
