Answer:

Step-by-step explanation:

So, when we dilate a triangle, it affects side measures.

So let's find it!

$10*0.4=4$

$30*0.4=12$

So, the sides of our new triangle is 4 and 12.

Let's find the area!

$\frac{4*12}{2} =24$

So, it is the first option! Hope this helps!

P.S. Stay Safe

Triangle TRE has vertices T(3,6), R(-3,10), and E(-9,4). Find the coordinates of point M if line TM is a median of triangle TRE

Sergeeva-Olga [200]

Answer:

The coordinate of point M = (-6,7)

Explanation:

The Median of a triangle is a line segment from a vertex to the midpoint of the opposite side of a triangle.

Given: $\triangle TRE$ has vertices T(3,6) , R(-3,10) and E(-9,4).

Here, line TM is a median of triangle TRE where M is the midpoint of RE.

The midpoint of M of the line segment from R(-3,10) to E(-9,4) is;

M = $(\frac{-3+(-9)}{2}, \frac{10+4}{2}) = ( \frac{-12}{2}, \frac{14}{2} )=(-6,7)$

Therefore, the coordinate of point M is, (-6,7).

Solve for x 5x + 4/2 = 7

aev [14]

Answer:

x=2

Step-by-step explanation:

5x+ $\frac{4}{2}$ = 7

5x+4 =7 (2)

5x+4=14

5x=14-4

5x=10

$\frac{5x}{5}$ = $\frac{10}{5}$

x=2
