Im assuming the base of the triangle is 4cm. The volume is

.
If the dimensions are tripled, the base is 12, the height is 24, and the length is 18. The volume is

, which is 27 times bigger.
If you are increasing each side by a factor of x, you are multiplying the original by
Answer:

Answer:
Step-by-step explanation:
The sum of the angles in a triangle = 180°
∠TUV + ∠TVU + ∠UVT = 180°
78° + 54° + ∠UVT = 180°
∠UVT = 48°
=> alternate angles (property of a parallel line), as SR is parallel to TU.
∠UVT = ∠SRV = 48°
The first one is 4n+7=15, the second one is 1/4(n-15), the third one is 1/4n-15, the fourth one is n/7=4, and the last one is n4+7=15
