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

De que numero es 552 el 8%menos

djyliett [7]

8% of 552 is 44.16. Look at the percent sign as a decimal and move it two places to the left, that'll give you 0.08. To find 8% of 552, look at it as 0.08 multiplied by 552. After you multiply you should get 44.16.
