Answer:
x=-35
Step-by-step explanation:
136+12x=-4(1-2x)
136+12x=-4+8x
+4 +4
140+12x-12x=8x-12x
140/-4=-4x/-4
x= -35
Answer:
208 ft
Step-by-step explanation:
in order to do this we need to find the area of the retangle:
(l x w) 14x20= 280ft
then the area of the rectangle:
a^2 + b^2 = c^2 ( hypotenus lenght )
c= 8.5
now we can plug in to find the area of the triangle, which is 12 (11.99)
then the area of the trapezium= 60
finally we can find the answer
280 - (60+12)= 208 ft :)
