4. k/6 = 8/16 5. 5.4/7 = 27/h 6. 8/11 = 4/y+2

use the cross products property to solve the proportion.

please show work

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cxd)(x)

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

Could somebody me with this radical simplification?
