2(area of s) + 2(area of f) + 2(area of ff) if s = side and f= opposite faces and ff = opposite faces.
2(4x3) + 2(3x10) + 2(4x10)=
24+60+80=
164 in squared
I'm assuming you meant to write

If so, then factor out an 'x' from the denominator and cancel

Answer: SAS
Step-by-step explanation:
Here ABC is a triangle, In which angle BAC is bisected by line AR where,
.
Thus in triangles ABR and ACR,
AB= AC ( given)
Therefore 
( by the property of angle bisector)
And,
(reflexive)
Thus by SAS postulate,
△ABR ≅ △ACR.
Therefore, Option D is correct.
12+49i
when you get i^2 it's the same as multiplying by -1 so
factoring it out will turn out like this
15i^2+40i+9i+27
instead of 15 i^2 multiply 15 x-1
-15+49i+27
12+49i
