Answer:

$\huge \boxed{ \boxed{z = 3}}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>let's solve:</h3>

$\sf simplify \: substraction : \\ \frac{3}{ \frac{z - 2}{z} } = 3z$
$\sf simplify \: complex \: fractio n : \\ \frac{3z}{z - 2} = 3z$
$\sf cross \: multiplication : \\ 3z = 3z(z - 2)$
$\sf divide \: both \: sides \: by \: 3z : \\ \frac{3z}{3z} = \frac{3z(z - 2)}{3z} \\ 1 = z - 2$
$\sf add \: 2 \: to \: bot h \: sides : \\ z - 2 + 2 = 1 + 2 \\ \therefore \: z = 3$

How do i find the area of a trapezoid (pictures provided)

scoray [572]

Answer:

(10x - 5) square units.

Step-by-step explanation:

Let the lengths of equal sides be x units.

Hence, AB + AD + DC = x + x + x = 3x

Therefore, BC = 3x - 2

$Area \: of \: trapezoid \\ = \frac{1}{2} (AD + BC) \times 5 \\ = \frac{1}{2} (x + 3x - 2) \times 5 \\ = \frac{1}{2} (4x - 2) \times 5 \\ = \frac{1}{2} \times 2 (2x - 1) \times 5 \\ = (2x - 1) \times 5 \\ = (10x - 5) \: {units}^{2}$
