-204 + 418 is 214 ft
-56 - 214 is -270 ft
I believe these should be correct.
Area = length x width
60 = (x+5) (x-2)
60 = x^2 + 3x -10
Subtract 60 from both sides:
x^2 +3x -70 = 0
Solve for x by finding 2 numbers when added together = 3 and when multiplied by each other = -70
x = -10 and 7
Since the sides have to be a positive number we need to use 7
The length = x+5 = 7+5 = 12 cm
The width = x-2 = 7-2 = 5 cm
The area is 14 because the triangles area is 6 and the rectangles area is 8
Answer:
2x -8
Step-by-step explanation:
4+2x-12= 2x -8
