Question

If k= 2, what is the value of k3 - (k - 10) + 4k?

Answer 1

Answer:

22

Step-by-step explanation:

Well, first, let's replace 2 with k, since k = 2.

2(3) - (2 - 10) + 4(2)

Now, let's do the equation inside the parenthesis first.

2(3) - (-8) + 4(2)

Now, multiply.

6 - (-8) + 8

Now, subtract.

14 + 8

Now, finish the equation.

14 + 8 = 22
