\[ x^{2}-2 x+\Delta=21+\boldsymbol{L} \] Qual valor de \( \Delta \) faria com que o lado esquerdo da equação foss quadrado de um polinômio de primeiro grau? ?

Solve the inequality. Express your answer using set notation and interval notation. Graph the solution set. \( -6 \leq 6-4 x \leq 3 \) The solution is expressed in set notation as \( \{x \mid \square\} \) The solution is expressed in interval notation as Choose the correct graph of the solution set below.

\( \sqrt {5\frac{9x8\% 5)4\pi 5}{}} \)
