Question

So 5(4d+8) = 40 so what does d= ?

Answer 1

d = 2. hope this helps :)

Answer 2

d = 0.

Explanation:

First, use the distributive property and distribute the 5.

The equation is now 20d + 40 = 40.

Subtract 40 from both sides to isolate the variable.

The equation is now 20d = 0.

Now you're thinking, this can't be possible! But really, 0 / 20 is possible. The answer is d = 0.
