what is the square root of 5z-2, then it says plus 7=10 First, subtract 7 from each side so you now have: sqrt(5z-2)=3. Then square each side, so you now have: 5z-2=9. Then add 2 to each side so you have 5z=11. Then divide each side by 5 and the answer is z=11/2. thanks ...

h(x)= x/(x-2) and g(x)= 2/x. Find and simplify h of g(x). I plugged g(x) into h: h(x)= (2/x)/[(2/x)-2] Now, would I multiply each by x, the Common Denominator? Therefore getting 2/(2-2x) which simplifies to 1-x?
