Answer:
option 3)
14% approx
Step-by-step explanation:
Given data
Initial= $18.00
final =$20.50
% increase= final - initial/initia *100
% increase= 20.50-18.0/18*100
% increase=2.5/18*100
% increase=0.138*100
% increase=13.8%
Hence the increase is 13.8%
=14% approx
Marcus should have substituted -10for b, not 10
Marcus should have subtracted 4(1)(25) in the square root
This equation, when solved correctly, only has one real number solution
So A, C, D
The radius is 14, if the diameter is 28. The radius is half of the diameter
