Triangle area= b*h/2
Plug in the values:
25*8/2
200/2
100
Final answer: 100 ft^2
You can add 9+1 then make ten and add 10 +1
- x + y = 7
y = x + 7
slope = 1
perpendicular slope = -1
at point (-1, -1),
y = mx + c
-1 = -1 (-1) + c
-1 = 1 + c
c = -1 -1
c = - 2
equation:
y = -x -2
y + x = -2 or - x - y = 2
