Step-by-step explanation:
Answer:
1.
-3|2x+6|=-12
|2x+6|=4
2x+6=4
2x+6=-4
x1=-5, x2=-1
2.
|x-2|+10=12
|x-2|=12-10
|x-2|=2
x-2=2
x-2=-2
x1=0, x2=4
Step-by-step explanation:
the correct formula for this is the heron's formula
which states that s=√s(s-a)(s-b)(s-c). Where s is a+b+c all divided by 2
s=√(13.5-12)(13.5-9)(13.5-6)
s=√(1.5)(4.5)(7.5)
s=√50.625
s= 7.11 or 7 to the nearest square unit
