aadc is formed by reflecting aabc across line segment ac, as shown in the figure.
if the length of ac is 4 units, the area of aadc is
square units.

Step-by-step explanation:

The area of initial triangle and the area of reflected triangle are the same, so

Find the area of triangle ABC using formula

In triangle ABC:

base = AC = 4 unitsheight = BE = 3 units

So,

Hence,

For range i think it’s area

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
