Answer:

f(-5) = 0

Step-by-step explanation:

Step 1: Define

f(x) = -2x² - 10x

f(-5) is x = -5

Step 2: Substitute and Evaluate

f(-5) = -2(-5)² - 10(-5)

f(-5) = -2(25) + 50

f(-5) = -50 + 50

f(-5) = 0

6×4=24 right so than how many 8 can get you to 24, so you do 8,16,24 or 8×3 So it's 8×3=24 (Your welcome ^.^)
