This is really obvious but the answer is 4 feet.
The steps below are presented in order to arrive to the value of k of the given equation.
First, multiply both sides of the equation by the variable k since the left-hand side of the equation has it in the denominator. This will be,
(k + 12/ k)(k) = 8(k)
Then, we simplify,
k + 12 = 8k
We then, subtract 8k to both sides of the equation,
k - 8k + 12 = 8k - 8k
Simplifying,
-7k + 12 = 0
Then, subtract 12 from both sides of the equation and divide both sides by -7. This will us the final answer of,
k = 12/7
Answer:
n = -7
Step-by-step explanation:
49 = -5n - 2n
combine like terms
-5 - 2 = -7
49 = -7n
divide both sides by -7
49/-7 = -7n/-7
49/-7 = n
49/-7 = -7
-7 = n
