Answer:
=14n⁴+8n²-9n+7
Step-by-step explanation:
(8n⁴-6n+8n²)+(6n⁴-3n+7)
=8n⁴-6n+8n²+6n⁴-3n+7
=8n⁴+6n⁴+8n²-6n-3n+7
=14n⁴+8n²-9n+7
Answer with explanation:
In Δ ABC and ΔD BC
∠A=∠D-------Given
∠ABC=∠DCB-------Each being 90° given in the Diagram.
Side, BC is Common.
⇒⇒Δ ABC ≅ ΔD BC-------[AAS]
When two triangles are congruent , their areas are equal.
So, Area(ABC)=Area (DCB)
Option B :⇒ A AS
