romanna [79]

Answer:

Step-by-step explanation:

The length of the median of a trapezoid equals one-half the sum of the lengths of the bases.

$\begin{array}{rcl}AB & = & \frac{1}{2}(JK + LM)\\\\& = & \frac{1}{2}(19 + 39)\\\\& = & \frac{1}{2}\times 58\\\\& = & \mathbf{29}\\\end{array}$

Which is equivalent to x3y–7? x cubed y Superscript 7 StartFraction x cubed Over y Superscript 7 EndFraction StartFraction x cub

butalik [34]

Answer:

$x^3y^{-7} = \frac{x^3}{y^7}$

Step-by-step explanation:

Given

$x^3y^{-7}$

Required

The equivalent

We have:

$x^3y^{-7}$

Apply the following rule of exponents

$a^{-b} = \frac{1}{a^b}$

So, we have:

$x^3y^{-7} = x^3 * \frac{1}{y^7}$

$x^3y^{-7} = \frac{x^3}{y^7}$
