La somma delle altezze di un parallelogramma, ventent l'area di \( 660 \mathrm{~cm}^{2} \), misura 35 cm e una è i \( \frac{4}{3} \) ell'altra. Calcola il perimetro. [154 \( \left.\mathrm{cm}^{2}\right] \) area di un parallelogramma è di \( 1014 \mathrm{~cm}^{2} \) e l'al-

Find the equations of the two straight lines which pass through the point \( (-3,2) \) and parallel to the two axes.

3. If the distance between the point \( (a, 2) \) and \( (3,1) \) be 8 , then a \( = \) ? \( \begin{array}{llll}\text { (1) } 2 \pm 3 \sqrt{15} & \text { (2) } 2-3 \sqrt{15} & \text { (3) } 3 \pm 2 \sqrt{15} & \text { (4) None of these }\end{array} \)

The volume of a cone varies jointly as the height and the square of the radius. Suppose a cone has the measurements \( V=5425.92 \) cubic meters, \( r=12 \) meters and \( h=36 \) meters. Step 1 of 2 : Find the constant of proportionality \( k \), rounded to two decimal places if necessary, and use it to write an equation that models the relationship.
