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

Rus_ich [418]

Answer:

Option C.

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

Step-by-step explanation:

we have

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

we know that

To find the zeros, equate the equation to zero

$x^{2}-576=0$

$x^{2}=576$

square root both sides

$x=(+/-)24$

therefore

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

Find the exact length of the third side. 51

Nesterboy [21]

Answer:

Step-by-step explanation:

You can use the Pythagorean Theorem to solve this:

$a^{2} + b^{2} = c^{2}$

The legs of the triangle are put into either a or b and the hypotenuse is put into c. In this case, they've already given you the hypotenuse, but now you need to find the leg:

$45^{2} + b^{2} = 51^{2}$

2025 + $b^{2}$ = 2601

Subtract 2025 from both sides:

2025 + $b^{2}$ = 2601

-2025 -2025

_____________

$b^{2}$ = 576

Square root:

$\sqrt{b^{2} } = \sqrt{576}$

b = 24
