Answer:B
If the equation above has infinitely many solutions for d, what is the value of a ?
A. -10 B. 10 C. 15 D. 20
Explanation: B The question states that there are infinitely many solutions to the equation. That means any real number should work for d. Plug in an easy number like 0 for every d in the equation to get . Simplify the equation to = , so a = 10, which is (B).
