Answer:
D) b = 
Step-by-step explanation:
First, move all the terms that do not include b to the left side with S:
S = 2ab + 2bc + 2ac
S - 2ac = 2ab + 2bc
Now, factor out 2b from the right side:
S - 2ac = 2b(a + c)
Divide both sides by 2(a + c):
b = 
Finally, multiply out the denominator:
b = 
Given:
The table of values for the function f(x).
To find:
The values
and
.
Solution:
From the given table, it is clear that the function f(x) is defined as:

We know that if (a,b) is in the function f(x), then (b,a) must be in the function
. So, the inverse function is defined as:

And,

...(i)
Using (i), we get

Now,


Therefore, the required values are
and
.
A) rhombus
b) trapezoid
c) square
d) rectangle
e) parallelogram
f) trapezoid
g) a parallelogram has 4 sides. The two opposite sides are always parallel.
A trapezoid has 4 sides. Only two opposite sides are parallel. The other two sides are not parallel.
h) a square has angles that must be 90degree big. A rhombus doesn’t.
