f(x) = (x - 6i)(x - (-2i))
f(x) = (x - 6i)(x + 2i)
f(x) = x² - 6xi + 2xi - 12i² (but i² = -1)
f(x) = x² - 6xi + 2xi + 12
<h2>
f(x) = x² - 4xi + 12</h2>
Answer: Its the second one.
Step-by-step explanation:
Answer: 591
Step-by-step explanation:
12 x 13= 156
12 x 5= 60 x 2= 120
12 x 5= 60/2= 30 x2= 60
5 x 12= 60
13 x 15= 195
195 + 60 + 60 + 120 + 156= 591
Având în vedere expresiile 4a + 7b + 6c și ecuațiile date a + b = 16 și b + 2c = 28.
4a + 7b + 6c pot fi scrise ca
<em>a + a + a + a + b + b + b + b + b + b + b + c + c + c + c + c.</em>
<em>= (a + b) + (a + b) + (a + b) + (a + b) + (b + 2c) + (b + 2c) + (b + 2c).</em>
Înlocuind valorile a + b = 16 și b + 2c = 28, ajungem
(a + b) + (b + 2c) + (b + 2c) + (b + 2c)
= 16 + 16 + 16 + 16 + 28 + 28 + 28
= 64 + 84
= 148.
<h3>
Prin urmare, 4a + 7b + 6c = = 148.</h3>
Answer:
6,265 votes
Step-by-step explanation:
The residents of a city voted on whether to raise property taxes. The ratios of yes votes to no votes was 5 to 7. If there were 10,740 total votes, how many no votes were there?
Given that :
Ratio of yes votes to no votes = 5 to 7
Yes votes : no votes = 5 : 7
Total votes = 10,740
The actual number of yes votes and no votes can be obtained thus :
Sum of ratio = (5 + 7) = 12
(ratio of vote / sum of ratio) * total votes
Number of no votes :
(Ratio of no votes / total ratio) * total votes
(7 / 12) * 10,740
0.5833333 * 10,740
= 6,265 votes
Number of no votes = 6,265 votes.
