Answer:

Step-by-step explanation:
Given : 
Solution:



Thus , 
Thus the solution is irrational since square root 7 does not have a perfect square and equal to 6+2square root of 14
Without context, d^3 + e^3 is equal to the equation you just showed.
First convert the equation in the form of <em>y= mx + </em><em>c</em>
The equation will be like = y = 6x-5
value of m = 6
The slope of perpendicular line will be = -1/m = -1/6
