Answer:
The answer is -a-bc+43
Step-by-step explanation:
Pull terms out from under the radical, assuming positive real numbers
Absolute value makes all things inside positive (make result positive)
so one example is
|x+1|=4
so if you had 3 in it woul dyhave
|3+1|=4
|4|=4
4=4
true
if -5
|-5+1|=4
|-4|=4
4=4

To find the area of the trapezoid you add the two bases then multiply by the base and divide by 2.
B1+b2= 24+16=40
40*h=40*12=480
480/2=240
D. 240 square feet.
