Question

tolong jawab 4 dan 5 kak plisssssssssssssssss

Answer 1

Penjelasan dengan langkah-langkah:

4. x → 4

[tex] \frac{12 + x - {x}^{2} }{ \sqrt{x } - 2 } [/tex]

[tex] = \frac{12 + 4 - {4}^{2} }{ \sqrt{4} - 2 } [/tex]

[tex] = \frac{16 - 16}{2 - 2} [/tex]

[tex] = 0[/tex]

5. x → 5

[tex] \frac{2x - 10}{ \sqrt{x + 4} - 3} [/tex]

[tex] = \frac{2(5) - 10}{ \sqrt{5 + 4} - 3} [/tex]

[tex] = \frac{10 - 10}{ \sqrt{9} - 3} [/tex]

[tex] = \frac{10 - 10}{3 - 3} [/tex]

[tex] = 0[/tex]

SEMOGA MEMBANTU
