Answer:

x = 19

Step-by-step explanation:

Assuming all angle measures are in degrees, the sum of them is 180:

(3x +16) +(4x -15) +(2x +8) = 180

9x +9 = 180 . . . . collect terms

x + 1 = 20 . . . . . . divide by 9

x = 19 . . . . . . . . . .subtract 1

The value of x is 19.

Complete the square to transform the quadratic equation into the form (x – p)2 = q.

ryzh [129]

The transformed equation is:

$(x-3)^2 = 23$

Step-by-step explanation:

We have to convert the equation in the form

$(x-p)^2 = q$

Given equation is:

$x^2-6x-8 = 6$

Adding 8 on both sides

$x^2-6x-8+8 = 6+8\\x^2-6x = 14$

In the given equation

a = x

b= ?

So,

$2.x.b = 6x\\b =\frac{6x}{2x}\\b = 3\\$

So 3^2 will be added on both sides

$(x)^2-6x+ (3) = 14+ (3)^2\\(x-3)^2 = 14+9\\(x-3)^2 = 23$

Hence,

The transformed equation is:

$(x-3)^2 = 23$
