With some extra effort, the radical can be removed from the denominator. That result is

The preferred form would be the one with the radical in the denominator, as it correctly shows the domain of the function to be x ≥ -7. The function actually is defined at x=74, which the "rationalized" form does not show.
Answer: 4 = n
Step-by-step explanation:
5n + 34 = -2(1-7n)
Distribute negative 2 to both 1 and negative 7n. You do this first due to the rules of PEMDAS
5n + 34 = -2 + 14n
Add two to both sides of the equation in order to further isolate (n) in 14.
5n + 36 = 14n
Subtract 5n from both sides of the equation so that the values with (n) are on one side of the equation.
36 = 9n
Divide nine from 36 and 9n in order to isolate (n).
4 = n
This then gives you your final answer.
Answer:
Step-by-step explanation:
Given: YX=HX,
m∠Y = m∠H
m∠ZXY=m∠KXH
ΔXYZ and ΔHXK are congruent triangles
so, YZ = HK (corresponding parts of congruent triangles are equal)
