K=-1 or k=5
either quantity could equal zero, so put each quantity equal to zero and solve for k.

Answer:
1. Re-writing an equation to remove all the variables.
Step-by-step explanation:
Backtracking is the procedure required for solving problems that has series of parts combined as one. It involves the retracing each part after one or two parts has been solved to solve the whole problem.
In mathematics when given an equation with variables, the solution can be obtained by calculating the values of each variable. To determine the final solution sometimes requires substitution procedure.
The best option that describe backtracking in maths-sense is; re-writing an equation to remove all the variables.
They're each divisors of 6460.
Answer:
x=20
Step-by-step explanation:
Look Angle A and D are Congruent so they equal the same
3x−10=2x+10
Subtract 2x from both sides
3x−10−2x=2x+10−2x
x−10=10
Add 10 to both sides.
x−10+10=10+10
x=20
