Answer:
12x + 15 = 12x - 15
Step-by-step explanation:
-5x - 25 = 5x + 25
-25 = 10x + 25
-50 = 10x
-5 = x
12x + 15 = 12x - 15
15 = -15 ( No solution )
12x + 15 = 3(4x + 5)
12x + 15 = 12x + 15
12x = 12x
0 = 0 ( True for all x's )
7x + 21 = 21
7x = 0
x = 0
Answer: SAS stands for side angle side and it means triangles are congruent by having the same side, angle, and side
Explanation: Let's say, two triangles both have the same angle, say 90 degrees. They also share two side lengths. Both triangles have a side length of 9 and another side length of 8.
The two triangles, sharing all these properties, must be congruent. This congruency is proven by SAS.
However, you must not get confused with other ways to prove congruency like ASA (Angle-Side-Angle)
Answer:
CD = 16.5
Step-by-step explanation:
To find the distance between two points, use this formula: 
point C can be info set 1: (10, -1) x₁ = 10 y₁ = -1
point D can be info set 2: (-6, 3) x₂ = -6 y₂ = 3
Substitute the information into the formula
