I believe your answer is C. But I’m not completely sure!
Answer:
48
Step-by-step explanation:
2 + 2 is 4, 1 - 4 is -3, 3 - 4 is -1 and +4 is 4 if you multiply these together, you will get 48.
The answer is D
You just move all numbers to the left and set it equal to 0
And then you add all same variables together
After that you use the quadratic formula
28 = k - 12
28 + 12 = k
40 = k
