D is the mid-point of the line segment AB where A is (1, 3) and B is (9, −1). A point has coordinates (, ) where and are variables. (i) Find the coordinates of D. (ii) If 2 = 20, write an equation relating .
(iii) It is given that AC and BC are equal in length.
Find an equation relating and and show that it can be simplified to
= 2 − 9.

step-by-step explanation:

its a wood chuck that can chuck wood

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
