Subtract: 2(k−4)−3(2k−1) .(1 point)
Responses
−6k−18
negative 6 k minus 18
8k−11
8 k minus 11
−4k−5
negative 4 k minus 5
−4k−11
negative 4 k minus 11
To find the answer, let's simplify the expression step by step:
2(k - 4) - 3(2k - 1)
= 2k - 8 - 6k + 3
= (2k - 6k) + (-8 + 3)
= -4k - 5
So, the correct response is -4k - 5.
