What is the simplified form of 3/4x+3+21/8x^2-14x-15
creativ13 [48]

Solution:

We have been asked to find the simplified expression of

3/4x+3+21/8x^2-14x-15=\frac{3}{4x+3} +\frac{21}{8x^2-14x-15}\\ \\ \text{We will have to make the denominator equal to add}\\ \\ \ 8x^2-14x-15=8x^2+6x-20x-15\\ \\ \ =2x(4x+3)-5(4x+3)=(4x+3)(2x-5)\\ \\  \frac{3}{4x+3} +\frac{21}{8x^2-14x-15}=\frac{3}{4x+3} +\frac{21}{(4x+3)(2x-5)}\\ \\ =\frac{3(2x-5)+21}{(4x+3)(2x-5)}\\ \\ =\frac{6x-15+21}{(4x+3)(2x-5)} \\ \\ =\frac{6x+6}{(4x+3)(2x-5)} \\

Point B is on line AC so that AB : BC = 2 : 1. Point D is on line AB so that AD : DB = 3 : 2. Find AD : DC
Leya [2.2K]

Firstly, we will draw figure

Let's assume

length of AC=x

we have

AB : BC = 2 : 1

so,

AB=\frac{2}{3} x

BC=\frac{1}{3} x

Point D is on line AB

and

AB=\frac{2}{3} x

AD : DB = 3 : 2

so, we get

AD=\frac{3}{5} *\frac{2}{3} x

AD=\frac{2}{5} x

DB=\frac{2}{5} *\frac{2}{3} x

DB=\frac{4}{15} x

now, we can locate these values

Firstly, we will find DC

DC=DB+BC

now, we can plug values

DC=\frac{4}{15} x+\frac{1}{3} x

DC=\frac{3x}{5}

we have got

AD=\frac{2}{5} x

now, we can find ratio

\frac{AD}{DC} =\frac{\frac{2}{5} x}{\frac{3x}{5}}

now, we can simplify it

\frac{AD}{DC} =\frac{2}{3}

so,

AD:DC=2:3...........Answer
