Find the total area of the figure below. a
240
b
192
c
288
d
144

a 240

Step-by-step explanation:

Area of rectangle 24 x 8 = 192

Area of triangle 24 x 4 = 96/2 = 48

192 + 48 = 240

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: you need to organize this better it does not make sense.
