Six dollars is the only answer that seems correct using the graph. Hope this helped.
Answer:
z=44/3
Step-by-step
Subtract the numbers 52-12=40
3z-4=40
Add 4 to both sides
3z-4+4=40+4
SImplify
3z=44
Divide both sides by 3
3z/3 = 44/3
z=44/3 or decimal form= 14.66
Your answer is no solution (because a negative square root doesn't exist)
first, you divide all sides by five and then take b, half it then square it
It is biggest to smallest I presume
