(x-3)2 + (x+ 2)2 = 40

Answer 1

Resposta:

$\boxed{\red{\mathsf{x = \frac{42}{4} }}}$

Explicação passo-a-passo:

$\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} }  \:  \: \mathsf {OI, TUDO \:  J\acute{O}IA \: ? \:  \:\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } }$

$\mathsf{(x - 3)2 + (x + 2)2 = 40} \\\mathsf{2(x - 3) + 2(x + 2) = 40} \\ \mathsf{2x - 6 + 2x + 4 = 40} \\\mathsf{2x + 2x - 6 + 4 = 40} \\ \mathsf{4x - 6 + 4 = 40} \\ \mathsf{4x - 2 = 40} \\ \mathsf{4x = 40 + 2} \\ \mathsf{4x = 42} \\ \boxed{\red{\mathsf{x = \frac{42}{4} }}}$
