I^2 = -1
i = √-1
Substitute the value of i in the equation:
(4+2i)(6-ki)=30
{4 + (2)(√-1)} {6 - k (√-1)} = 30
( 4 + 2√-1)(6 -k√-1) = 30
24 - 4k√-1 + 12√-1 -2k (-1) =30
24 - 4k√-1 + 12√-1 +2k =30
-4k√-1+12√-1 + 2k - 6 =0
-2√-1(2k -6) + (2k-6) =0
(-2√-1 +1)(2k-6)=0
2k -6 =0
2k = 6
k= 3
So, the value of k is 3.
Answer:
I don't know please very sorry for your
Answer:
n = 40
Step-by-step explanation:
n - 12 = 28
add 12 to both sides to remove the negative 12
n = 28 + 12
n = 40
The area of a triangle is 1/2bh, which means The second choice is correct :)
Hope this helps!!
The answer is 43.6 liters
Explanation:
So we want to find out how many liters are in 48 quarts. The first step would be to find other how many liters are in 1 qt, which is about 0.95 liters. Now that we know there are 0.95 liters in 1 qt, to solve for 48 qts, we multiply by 0.95. 0.95 x 48 = 45.6. Since 43.6 is closest to our rounded answer, 45.6, there are about 43.6 liters in 48 qts.
