Answer:

A. addition property of equality; division property of equality

Step-by-step explanation:

$4\left(x-2\right)=6x+18$ [ given ]
$4x - 8 = 6x +18$ [ distributive property ]
$-2x - 8 = 18$ [ addition property of equality ]
$-2x = 26$ [ addition property of equality ]
$x = -13$ [ division property of equality ]

Quadrilateral KLMN is a rectangle. The coordinates of L are L(1,-4) and the coordinates of M are M(3,-2) find the slopes of side

m_a_m_a [10]

We can start by finding the gradient of LM
$m= \frac{ y_{2}- y_{1} }{x_{2} - x_{1} } = \frac{-2--4}{3-1} = \frac{2}{2}=1$

Two perpendicular lines will meet the requirement $m_{1}$ × $m_{2}$ =-1
Two parallel lines have equal gradients

NM is perpendicular to LM, hence the gradient of NM is -1
KN is a line that is parallel to NM, hence the gradient is 1
KL is perpendicular to LM, hence the gradient of KL is -1
