Answer:
The correct option is A.
Step-by-step explanation:
It is given that DEFG is a parallelogram.
Draw the diagonals DF and EG. Place point H where DF and EG intersect.
In triangle HGD and HEF
,
∠HGD ≅ ∠HEF (Alternate Interior angle)
∠HDG ≅ ∠HFE (Alternate Interior angle)
By the definition of a parallelogram, the opposite sides of a parallelogram are congruent.
DG ≅ EF (Opposite sides of parallelogram)
According to ASA postulate, two triangles are congruent if any two angles and their included side are equal in both triangles.
So, by using ASA criterion for congruence we get,
ΔDGH ≅ ΔFEH
Since corresponding sides of congruent triangles are congruent, therefore
GH ≅ EH (CPCTC)
DH ≅ FH (CPCTC)
Option A is correct.
Answer:
the second one it is a function.
Answer:
a
Step-by-step explanation:
x^2 -x
A linear equation can't have an exponent when fully simplified
STEP-BY-STEP SOLUTION:
= a^3 - 4a^2 + 12 - 3a
= a^2 ( a - 4 ) + 3 ( 4 - a )
= a^2 ( a - 4 ) - 3 ( a - 4 )
= ( a - 4 ) ( a^2 - 3 )
