Answer:
b because if your going to the left that means is negative and we are going up that means it's positive
Divide 4 to both sides of the equation
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
4x-2=18
-2 on both sides
4x=16
divid by 4 on both sides
x= 4
