x =(-2-√-12)/8=(-1-i√ 3 )/4= -0.2500-0.4330i
x =(-2+√-12)/8=(-1+i√ 3 )/4= -0.2500+0.4330i
x = 1/2 = 0.500
Answer:
0.4655172413793
Step-by-step explanation:
45/87 ×-9/10 i
405÷870
The simplest answer would just be 14:19
However the unsimplified answer is 1260:1710
Take the number of weeks as x
12x = 544 - 100
x =444/12
x = 37
Thus it would take her 37 weeks to buy her a laptop
