Answer:
x= 25/3 or 8.333333
Step-by-step explanation:
you add 11 to 10 to get 21
3x-4=21
add 4 to both sides, which will cancel out the (-4)
3x=25
divide each term by 3 to get x by itself
3x/3 = 25/3
you will then get x=25/3

Answer:
B
Step-by-step explanation:
Reflection is a transformation that preserves lengths.
Triangle XYZ, with side lengths XY = 7 in, YZ = 5 in, XZ = 4 in, is reflected across the x-axis to result in △X'Y'Z'.
This means that corresponding sides have the same lengths:
- XY = X'Y' = 7 in;
- XZ = X'Z' = 4 in;
- YZ = Y'Z' = 5 in.
Find the perimeters of both triangles:

Hence, only option B is true.
