1. Quadrilateral ABCD with vertices A(- 4, 1) B(- 2, 3), C(0, - 2) and D(- 5, - 2) : k = 3

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

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

if we simplify it:

8x-26=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

the answers might not be correct use at own risk

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

i belive false if so your welcome if not well idk
