Answer:
im not sure im so sorry! qwq
Step-by-step explanation:
It would be 28.5. First, you would find the area of the smaller triangle by using the formula a=.5bh (area=.5xbasexheight) and then when you get that, you should get 6. Then, you do the same for the larger triangle and you should get 22.5. Then, 22.5 + 6 = 28.5, giving you that answer.
Good morning
x-3y=-3
x+3y=9
Solve x-3y=-3 for x
Add 3y to both sides
x-3y+3y=-3+3y
x= 3y-3
Substitute 3y-3 for x in x+3y=9
x+3y=9
3y-3+3y=9
Simplify both sides of the equation
6y-3=9
Add 3 to both sides
6y-3+3=9+3
6y=12
Divide both sides by 6
6y/6=12/6
y=2
Substitute 2 for y in x=3y-3
x=3y-3
x= (3)(2)-3
x= 6-3
x= 3
Final answer : X=3, Y=2
I hope that's help !
