1) √72z² = 6z √2 B.
2 * 6 * 6 = 72
2) C. √6
3 * 3 √6 - 4 * 2 √6 = 9√6 - 8√6 = √6
+5 on both sides
So you're left with 2x=33
Divide 2 from both sides
X= 16.5
Answer:
Two negative make a positive so this equation is basically 39 = n + 12 so you need to subtract 12 from each side. This makes it n = 27
