The area of a Triangle is 1/2BH (B=Base length, H=Height)
When looking at the points, we can figure out the following:

The distance between the two points at the base is 8 (to get from -4 to 4 you must add 8) and the height is 4 (to get from -4 to 0 as well as 0 to 4, the distance is 4).

Now we plug in our values:
Area= 1/2(8)(4)
=1/2(32)
=16 Units squared

Therefore, your answer is 16 units squared.

I hope this Helps!

Please help me prove that ED is congruent to BA! I thought I had it right by proving right and vertical angles, but I’m missing

Vikki [24]

Step-by-step explanation:

$\overline{DA} \text{ bisects } \overline{EB}$ is given

$\overline{BC} \cong \overline{EC}$ definition of bisect

$\overline{EB} \perp \overline{ED}, \, \overline{EB} \perp \overline{BA}$ are both given

$\angle B, \, \angle E \text{ are right angles}$ definition of perpendicular

$\angle B \cong \angle E$ because all right angles are congruent

$\angle{ACB} \cong \angle{DCE}$ vertical angles are congruent

$\triangle{ACB} \cong \triangle{DCE}$ ASA (angle-side-angle)

$\overline{ED} \cong \overline{BA}$ CPCTC (corresponding parts of congruent triangles are congruent)

Solve for x:|3x + 12|=18

inessss [21]

$|3x+12|=18\iff3x+12=18\ or\ 3x+12=-18\\subtract\ 12\ from\ both\ sides\\\\3x=6\ or\ 3x=-30\ \ \ \ |divide\ both\ sides\ by\ 3\\\\\huge\boxed{x=2\ or\ x=-10}$
