Answer:
x = 9
Perimeter = 74
Area = 342
Step-by-step explanation:
First, find x. to do so, set your formula up as
18 = 8x - 54
18 + 54 = 8x
72 = 8x
72/8 = x
9 = x
Now that you have x, find your missing side
2x + 1 = y, x
2 * 9 + = y
19 = y
Your perimeter is P = 2(l+W)
P = 2(18 * 19)
P = 74
Your area is A = wl
A = 19 * 18
A = 342
To answer this item, we are to use the concept of combination. The equation is as follows,
nCr = (n!)/((r!)(n - r))!
Substituting the known values in the equation,
3C2 = 3!/(2!)(3-2)! = 3
Hence, the answer to this item is 3.
