You use the discriminant (b²-sqr(4ac))/2a and if sqr(4ac) inferior to 0 then use i = sqr(-1)
1.) C is the correct choice
4.) B is the correct choice
Answer:
B. 1150
Step-by-step explanation:
14000-5000=9000 sales over 5000
9000 x .10=900 commission
250 (salary)+ 900 (commission)=1150 total
If 4=2^2
8=2^3
(2^)2x+10=(2^)6x
(2^)6x-(2^)2x=10
(2^)2x×7=10, where x has no real value
