Answer:
6 √(10) i (the last option)
and 6i√10
Step-by-step explanation:
√-40 = √4 * √-10 = 2√(10) i
3 * 2√(10) i
= 6 √10 i
Also 6i√10 is equivalent
Answer:
0.65 is the correct answer
Answer:
-0.14 * 0.12 = -0.0168
Step-by-step explanation:
You could multiply both numbers by 100 to make them whole integers.
-0.14 * 100 = -14
0.12 * 100 = 12
-14 * 12 = -168
Now divide by 100 twice.
-168 / 100 = -1.68 / 100 = -0.0168
Answer:x=4y
Step-by-step explanation:as you can see x is 4 times more than y.
3 - (5x + 4/5) = x/2
3 - 5x - 4/5 = x/2
3 - 4/5 = x/2 + 5x
15/5 - 4/5 = x/2 + 5x
11/5 = x/2 + 5x.....multiply both sides by 10
22 = 5x + 50x
22 = 55x
22/55 = x
2/5 = x
