1) property of distribution: 30 = -30n - 30
2) inverse property of addition: 60 = -30n
3) inverse property of multiplication: -2 = n
step 2: subtract 30 from both sides
step 3: divide -30 from both sides
Answer: Variant C
Step-by-step explanation:
f(x) = 3x^2 − 4
For finding f(-2) just replace x with - 2 like this:
f(-2)=3*((-2))^2-4=3*4-4=12-4=8
The answer is 5 x -3 + 4 x 2 / 2 = -15 + 8 / 2 = -11
