Answer: The area common to both triangle is 31.77 sq. cm.
Step-by-step explanation:
Since we have given that
30-60-90 triangles are placed.
So, the ratio of sides would be

Since Hypotenuse = 12 cm
So, it becomes,

So, Base would be

and Perpendicular would be

So, Area common to the both triangles would be

Hence, the area common to both triangle is 31.77 sq. cm.
The common factors are 1 and 2.
Factors of 74.48:

Answer:
see explanation
Step-by-step explanation:
A rational number can be expressed in the form
← where a and b are integers
An example is

- 5 can be expressed as
and is therefore rational
Numbers which are not rational are irrational
π and
are examples of irrational numbers
Just replace x^2+4 with a
factor out on left side
(x^2+4)^2+32=12(x^2+4)
replace x^2+4 with a
a^2+32=12a
minus 12a both sides
a^2-12a+32=0
solve
factor
what 2 numbers mulitply to get 32 and add to get -12
-4 and -8
(a-4)(a-8)=0
set each to zero
a-4=0
a=4
a-8=0
a=8
remember
a=x^2+4
so
4=x^2+4
0=x^2
0=x
8=x^2+4
4=x^2
+/-2=x
x=-2, 0, 2
