Answer

Given expression,

$(81x^2-25)\times \dfrac{6}{18x+10}$

We have to find the value of x for which the expression is undefined.

Simplifying the given expression

$((9x)^2-5^2)\times \dfrac{3}{9x+5}$

$(9x-5)(9x+5)\times \dfrac{3}{9x+5}$

$3(9x-5)$

On solving we can see that the expression is defined for all value of x.

Answer:

x = 12

Step-by-step explanation:

(10x - 20)° and (6x + 8)° are on the straight angle and they are both equal 180°

to find the value of x:

10x - 20 + 6x + 8 = 180

10x + 6x = 180 + 20 - 8

16x = 192

x = 192/16

x = 12
