Select the correct answer.
stiks02 [169]

Answer:

\dfrac{31}{2}+\dfrac{27}{2}i

Step-by-step explanation:

The given complex number is:

z=\dfrac{(2+3i)(4-7i)(1+i)}{(1^2-i^2)}

Firstly we can solve (2+3i)(4-7i)(1+i)

= 2(8)+2(-7i)+4(3i)+3i(-7i²)× (1+i)

= (16-14i+12i-21i²i)× (1+i)

Since, i² = -1

= (16-14i+12i-21(-1)i)× (1+i)

= (16-14i+12i+21)× (1+i)

= (29-2i)(1+i)

= 31+27i

Denominator : (1-i²)

= (1-(-1))

= 2

\dfrac{(2+3i)(4-7i)(1+i)}{(1^2-i^2)}=\dfrac{31+27i}{2}\\\\=\dfrac{31}{2}+\dfrac{27}{2}i

Hence, the correct answer is \dfrac{31}{2}+\dfrac{27}{2}i.

Answer:

His mistake was he didn't multiply 3(4) when he was opening the parenthesis

Step-by-step explanation:

Correct solution:

12x – 5 = 3(x + 4)

Open parenthesis

12x – 5 = 3x + 12

Collect like terms

12x - 3x = 12 + 5

9x = 17

x = 17/9

x = 9 8/9

Incorrect solution:

12x – 5 = 3(x + 4)

His mistake was he didn't multiply 3(4) when he was opening the parenthesis

12x – 5 = 3x + 4

12x = 3x - 1

9x = -1
