Answer:

3 things :)

Step-by-step explanation:

#1. I have reported these websites to many brainly users and I hope they all stay safe.

#2. As you can see in the model there are 10+ (positives) and -4 (negatives)

and when you subtract the positives and the negatives (10 -4) you would get 6

#3. The equation that represents the model would be when you divide the negative and the positive in this case -4/10 which would equal -2/5

What is the area of triangle EDF?

Ann [662]

Answer:

4.5

Step-by-step explanation:

∠BAC ~ ∠EDF means that the triangles are similar. So the legs of the triangle share the same proportions, even if the sizes are different.

Since they share the same proportions, the same operations can be performed on each base to find the area.

The answer can be found with the knowledge that the area of a triangle is half of the height * width. You know the width of ∠BAC is 4, and the area is 8, so 16 (the area doubled) / 4 is the height. The width and height of ∠BAC are the same, and since the proportions are also the same, the width and height of ∠EDF are both 3. So the area is the width (3) times the height (3) divided by 2.

3*3 = 9

9/2 = 4.5

So the area is 4.5
