Answer:
k = 0
Step-by-step explanation:
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 6 from both sides
k² + 6 (-6) = 6 (-6)
k² = 0
Isolate the k. Root both sides
√(k²) = √(0)
0 is your answer for k

z = 1
15z + 35 = 50
15z = 50 - 35
15z = 15
z = 15/15
4^3 and 8^2
