Answer:B
Step-by-step explanation:
4x2 =121
4x2-121=0
using the general formula
[-b( +/-) √b2-4ac]/2a
a=4, b= 0, c=-121
x= [0 ( +/-)√02-(4*4*-121)]/2.4
= ( +/-)√1936)/8 = ( +/-)5.5
x =5.5
x = -5.5

Answer:
$2200
Step-by-step explanation:
$4800 premium for 2 years means for 2* 12 = 24 months, thus each month, the insurance expense is:

200 * 100 = $2200
