What is the area of the triangle ABC, given A(-1.4), B(2,-2), and c(-3,-2). 30 square units

6.3 square units

15 square units

18.03 square units.

x=30

step-by-step explanation:

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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

what's the question?

step-by-step explanation:

there is no question.
