Answer:
VW=36
VT=27
Step-by-step explanation:
VW is the midsegment of the triangle
so
VW=72/2
=36
VXT is a right angle triangle
so
a²+b²=c²
a=√c²-b²
a=√45²-36²
a=√(45-36)(45+36)
a=√9×81
a=√9×√81
a=27
therefore
VT=27
Answer:

Step-by-step explanation:
Factor the equation
using formula for difference of the cubes:

then

1. The equation
has real solution 
2. The equation
has negative discriminant
then it has two complex solutions
