Answer:
f(-4) = 72, f(x + 5) = 3x² + 23x + 36
Step-by-step explanation:
f(-4) = 3(-4)² - 7(-4) - 4
= 48 - (-28) - 4
f(-4) = 72
f(x + 5) = 3(x + 5)² - 7(x + 5) - 4
= 3(x + 5)(x + 5) - 7(x + 5) - 4
= 3(x² + 10x + 25) - 7(x + 5) - 4
= 3x² + 30x + 75 - 7x - 35 - 4
f(x + 5) = 3x² + 23x + 36
1 way is (100 divide by 5) +(35 divide by 5)
2 way is (50 divide by 5) + (85 divide by 5)

Answer:
Step-by-step explanation:
1/2 = 2m
2m/2 = 1/2 divided by 2
1/2 * 1/2 = 1/4
m = 1/4
m = 0.25
Answer: m = 1/4 or 0.25
