The choices b and c are equivalent to 
.
Step-by-step explanation:
Step 1:
First, we need to bring the fraction to its simplest form. To do so, we divide the numerator and the denominator by the greatest factor.
The greatest factor for 4 and 6 is 2. So we divide it by 2.
So 
.
Step 2:
Similarly, we need to do the same for all the given four options.
a. 
, the greatest factor for 2 and 4 is 2. So we divide the fraction by 2.
So 
.
b. 
, the greatest common factor for 8 and 12 is 4. So we divide the fraction by 4.
So 
.
For options c and d, 1 is the greatest factor so they cannot be simplified. They remain as they are.
Step 3:
So options b and c are equal to the simplification of i.e. 
.
4.1*4.1*6=100.86 inches^2
Answer:

dont come for me if im wrong
X=90 which (180-90) is 90 for m and n
Answer:
AC=16 units
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. It was given that diagonals AC and BD intersect at point E.
This implies that: 
.
We substitute the expression for x, we get:
.
Group similar terms to get:
.
.
AC = 2(12-4x)
AC=2(12-4(1))
AC=2(8)
AC=16
