By the external angle of a triangle theorem

m < ABD = m < BDC + m < BCD

That is 5x + 2 = x^2 - 1 + 4x - 3

x^2 + 4x - 5x - 1 - 3 - 2 = 0

x^2 - x - 6 = 0

(x - 3)(x + 2) = 0

x = 3, -2

x cannot be -2 because that would make the external angle, 5x-2 negative.

Answer x = 3

Which statement about g(x)=x^2-576 is true

Ipatiy [6.2K]

Answer:

c. the zeros, -24 and 24, can be found when 0= (x+24)(x-24).

Step-by-step explanation:

The given function is

$g(x)=x^2-576$

When we equate the function to zero, we obtai;

$x^2-576=0$

Use difference of two squares:

$x^2-24^2=0$

$(x-24)(x+24)=0$

Use the zero product property to obtain;

$x-24=0,\:and\:x+24=0$

This implies that;

$x=24,\:and\:x=-24$

The correct choice is C
