y = x + 6
z = xy - 8

Answer 1

Verified answer

Jawaban:

x² + z² = 57.290

Penjelasan dengan langkah-langkah:

x = 13

y = x + 6

y = 13 + 6

y = 19

z = xy - 8

z = ( 13 x 19) - 8

z = 247 - 8

z = 239

maka

x² + z² = ( 13)² + ( 239)²

= 169 + 57121

= 57.290

..

[tex]x^2 + z^2 = x {}^{2} + ((x)(y)- 8) {}^{2} [/tex]

[tex]x^2 + z^2 = x {}^{2} + ((x)(x + 6) - 8) {}^{2} [/tex]

[tex]x {}^{2} + z { }^{2} = 13 {}^{2} + ((13)(13 + 6) - 8) {}^{2} [/tex]

[tex]x {}^{2} + z { }^{2} = 169 + ((13)(19) - 8) {}^{2} [/tex]

[tex]x {}^{2} + z { }^{2} = 169 + (247 - 8) {}^{2} [/tex]

[tex]x {}^{2} + z { }^{2} = 169 + 239 {}^{2} [/tex]

[tex]x {}^{2} + z { }^{2} = 169 + 57121[/tex]

[tex]x {}^{2} + z { }^{2} = \boxed{\bold{\underline{57290}}}[/tex]
