Since it's a regular pentagon, all it's sides are equal so let's solve for x

$\hookrightarrow \: 3(x - 1) = 5x - 6$

$\hookrightarrow \: 3x - 3 = 5x - 6$

$\hookrightarrow \: 3x - 5x = - 6 + 3$

$\hookrightarrow \: - 2x = - 3$

$\hookrightarrow \: x = \dfrac{ - 3}{ - 2}$

$\boxed{\boxed{x = \dfrac{3}{2} }}$

now let's find the measure of each side, i.e

$\hookrightarrow \: 5x - 6$

$\hookrightarrow \: (5 \times \dfrac{3}{2}) - 6$

$\hookrightarrow \: \dfrac{15}{2} - 6$

$\hookrightarrow \: 7.5 - 6$

$\mathrm{\hookrightarrow \: 1.5 \: units}$

perimeter = 5 × side length ( for a regular pentagon )

$\hookrightarrow \: 1.5 \times 5$

$\boxed{ \boxed{ \: \: \: \: \: \: \: \: 7.5 \: \: units \: \: \: \: \: \: \: }}$

The table represents a linear function.

svet-max [94.6K]

Pick 2 sets of points from ur table...

(-4,-16)(-2,-6)
slope = (y2 - y1) / (x2 - x1)
slope = (-6 - (-16) / (-2 - (-4) = (-6 + 16) / (-2 + 4) = 10/2 = 5

u could pick any 2 of ur sets of points.....it will come out the same...let me show you...
(2,14)(4,24)
slope = (y2 - y1) / (x2 - x1)
slope = (24 - 14) / (4 - 2) = 10/2 = 5...see, it is the same no matter what 2 sets of points u choose)
