Answer:
1
Step-by-step explanation:
just substitute -2 for x
1. Yes.
Since, to be a triangle, the sum of the smallest two sides must be greater than the third side, the triangle can be formed.
3 + 22 > 24
2. This triangle is a right triangle.
180 - 60 - 30 = 90
90 degrees is a right angle.
Hope this helps!

Answer:
All the coordinates are changed to
(x, y) ⇒ (2x, 2y)
Step-by-step explanation:
Given - A triangle is to be dilated with the origin as the center of dilation and with a scale factor of 2.
To find - Which answer choice correctly maps this dilation algebraically?
Proof -
Let ABC is a triangle where A, B, C are the vertices of the triangle respectively.
Now,
Let the coordinates be (x, y)
If a triangle is to be dilated with the origin as the center of dilation and with a scale factor of a , then the coordinated be changes as
(x, y) ⇒ (ax, ay)
Here given , a = 2
So, all the coordinates are changed to
(x, y) ⇒ (2x, 2y)
