Question 67703This question is from textbook Algebra and Trigonometry with Analytic Geometry

: To Whom It May Concern:
Your assistance is greatly appreciated.
Didn't have the textbook info yesterday when I submitted these questions.
The questions are from a quiz that I took for my online course.

Find the value of k that completes the square for x2 + 10x + k?

Use completing the square or the quadratic formula to find the solutions to the equation x2 – 4x + 2 = 0

Find the solutions to the equation: x2 + 2x + 5 = 0?

Find the solutions to the equation: x + 7/x = 8?

Solve the equation: x – 3 – sqrt x – 1 = 0?

Solve the equation: x + 2 – 2 sqrt x + 2 = 0?

Solve the inequality 2 | x – 10 | < 3 and express the solution as an interval?
Please get back to me ASAP since I'm studying for my final exam.
