Answer:

Step-by-step explanation:
Given the information:
- A'B'C' reflection over x = −1
- dilation by a scale factor of 4 from the origin
<=> the two triangles are similar to each other, triangles are similar if they have the same shape, but can be different sizes, so A″B″C″ is 4 time bigger than ABC
=> the relationship between ΔABC and ΔA″B″C″
= 
We choose C.
Hope it will find you well.
Answer:
i dont see the question
Step-by-step explanation:
It would be: 39/40 * 100 = 3900/40 = 97.5%
Height = Volume / area of base
Area of base = 3.5 x 4 = 14 sq. inches.
Height = 84 / 14
Height = 6 inches.
