Identify the quotient in the form a + bi. HELP ASAP PLEASE!!
Artist 52 [7]

Solving \frac{4-5i}{2+3i} we get -\frac{7}{13}-\frac{22i}{13}

Option A is correct.

Step-by-step explanation:

We need to find the result of \frac{4-5i}{2+3i}

We need to remove i from the denominator. For removing i Multiplying and dividing by 2-3i:

\frac{4-5i}{2+3i}*\frac{2-3i}{2-3i}

Solving:

=\frac{4-5i*2-3i}{2+3i*2-3i}\\=\frac{4(2-3i)-5i*(2-3i)}{(2)^2-(3i)^2}\\=\frac{8-12i-10i+15i^2)}{4-9i^2}\\We\,\,i^2=-1\\=\frac{8-12i-10i+15(-1))}{4-9(-1)}\\=\frac{8-12i-10i-15}{4+9}\\=\frac{8-15-12i-10i}{13}\\=\frac{-7-22i}{13}\\=-\frac{7}{13}-\frac{22i}{13}

So, solving \frac{4-5i}{2+3i} we get -\frac{7}{13}-\frac{22i}{13}

Option A is correct.

If PM = 2x - 5, PN = 6x, and MN = 5x + 4, what is the value of x?
Vadim26 [7]

Answer:

The required value of x = 3

Step-by-step explanation:

For better understanding of the solution, see the attached figure :

The given three points are collinear to each other and the point P lies somewhere between the end points of the line MN

So, to find the value of x we can use the relation : Sum of Mid segments PM and PN is equal to complete length of the line segment MN

⇒ PN + PM = MN

⇒ 6·x + 2·x - 5 = 5·x + 4

⇒ 8·x - 5·x = 4 + 5

⇒ 3·x = 9

⇒ x = 3

Hence, The required value of x = 3
