Answer:
2.7 in²
Step-by-step explanation:
Area of ∆BAC : ∆Area of EDF = BC² : EF² (based on the area of similar triangles theorem)
Thus:







Area of ∆EDF = 2.7 in²
Answer:
Undefined
Step-by-step explanation:
Answer:
y=-2x-4
Step-by-step explanation:
6x + 3y=-12 subtract 6x to other side
3y=-12-6x divide 3 to every number
1y=-4-2x
4x + 6y = 8z +34
4x+6y - 8z = 34
