Answer:
Perimeter: 33.7 mm
Area: 54 mm
Step-by-step explanation:
If you do 12 + 9.7 + 12 you will get the perimeter, and to get the area you would use the formula A = 
x base x height. Since the base is 12 and the height is 9, you would do 12 x 9 x 0.5 to get 54 mm for the area of the triangle.

Step-by-step explanation:
Answer:
y = -5(x +6) -9
Step-by-step explanation:
The point-slope form of the equation for a line can be written as ...
y = m(x -h) +k
for a line with slope m through point (h, k).
You have m=-5 and (h, k) = (-6, -9). Filling in these values gives ...
y = -5(x -(-6)) -9
Simplifying a bit, you get ...
y = -5(x +6) -9
X=-84. 3(x-6)+24=50+4(x+10)
distrubute. 3x-18+24=50+4x+40
move terms. 3x+6=90+4x
collect like terms 3x-4x=90-6
subtract -x=84
divide by -1. x=-84
