Какое из приведенных неравенств будет линейным неравенством с одной переменной: \[ \begin{array}{l}\text { А) } x \geq 15 \\ \square \text { B) } x+4 \geq y \\ \square \text { C) } 5+9<27 \\ \square \text { D) } y>6,5 \\ \square \text { E) } 2 x>-2 \\ \square \text { F) } x y \leq \frac{3}{7}\end{array} \]

Lesson 14: What Do You Know About Polynomials? Cool Down: How Would You Factor? A polynomial \( D(x)=3 x^{3}-2 x^{2}-15 x+14 \) has known factors \( (x-2) \) and \( (x-1) \). Would you use a diagram, long division, or some other method to rewrite the expression for D in factored form? Explain your reasoning.

Soluciona las siguientes integrales definidas. a. \( \int_{1}^{3}\left(2 x^{4}+5 x^{3}+x^{2}-2 x+3\right) d x \) b. \( \int_{2}^{4}\left(3 x^{2}+x\right) d x \)
