This will be:
[√9]/[(3-2i)+(1+5i)]
simplifying the above we get:
√9/(3+1-2i+5i)
=√9/(4+3i)
rationalizing the denominator we get:
√9/(4-3i)×(4-3i)/(4-3i)
=[√9(4-3i)]/(16+9)
=[3(4-3i)]/25
=(12-9i)/25
Answer: (12-9i)/25
Hello,
|BD|=61
|JS|=|JB|+|BS|=84
|BS|=18 ==>|JB|=84-18=66
|JD|=|JB|+|BD|=66+61=127
Answer:
30 and 20 respectively
Step-by-step explanation:
Let the number of sofas to be built be s and the number of recliners be r.
For the time part, we have the following equation:
8s + 6r = 340
For the money part:
180s + 105r = 6750
Now let’s solve these equations simultaneously.
Let’s change the form of the second equation:
180s + 17.5(6r) = 6750
From the first equation, 6r = 340 - 8s
Insert this into the third equation
180s + 17.5(340-8s) = 6750
180s + 5950 - 140s = 6750
40s = 6750 - 5950
40s = 800
s = 20
Substitute the value into the first equation
8(20) + 6r = 340
6r + 160 = 340
6r = 180
r = 30
The additive inverse of -7 is 7, the additive inverse of a number is when added to any number equals 0. So the additive inverse of -14=14 and 7=-7.
X = 30
Y = 20
