Answer:
The length of the longest section x = 36 ft
Step-by-step explanation:
Total length of the wire = 51 ft
Let first section of wire = x
Second section of wire = y
Third section of wire = z
According to given data
x = 3 y & y = 4 z
Total length of the wire = x + y + z = 51


y = 12
x = 3 × 12 = 36

Therefore the length of the longest section x = 36 ft
Answer:
The answer is D
Step-by-step explanation:
f(x) = 3x² - 12x + 4
f(-2) = 3(-2)² - 12(-2) + 4
= 12 + 24 + 4
= 40
