Answer:
D
Step-by-step explanation:
positive 4, positive one
The net shows an equilateral triangle with side length 24 cm.
The area of an equilateral triangle of side length s is ...
... A = (√3)/4·s²
Using the above side length, the area is
... A = (√3)/4·(24 cm)² = 144√3 cm² ≈ 249.4 cm²
Your best choice is the first one:
... A) 249.6 cm²

The multiple zero is x = -4.
The multiplicity is 2 because there are two values of x.
If it is cylindrical, the circumference is the diameter x pi. If it is rectangular, it is the length of the sides added together.
