n(5 + 2) - 15

n = 5

Step 2: Simplify

Step 3: Evaluate

  1. Substitute in n:                    7(5) - 15
  2. Multiply:                               35 - 15
  3. Subtract:                              20

Answer:

20

Step-by-step explanation:

So, the question said that n=5 so we will input 5 to replace n.

5(5+2)-15

Now, solve the problem

5(5+2)-15

5 x 7- 15

35-15

20

Thus, the answer is 20
