Then

so that the critical point at ′()=0
f

Answer:
5
Step-by-step explanation:
The correct answer is D, since a rotation of 360 has no effect, since the figure does a whole turn and returns where it was.
Answer:
Hello! answer: 75
Step-by-step explanation:
5 × 5 = 25 for a square
for a triangle 5 × 5 = 25 25 ÷ 2 = 12.5 12.5 × 4 = 50 25 + 50 = 75 therefore the total area is 75 HOPE THAT HELPS!
