Which represents the solution set of 5(x+5)< 85

5 (x + 5) <85
 For this case, the first thing we will do is clear the expression step by step.
 Step 1:
 Pass the five to divide:
 5 (x + 5) <85
 (x + 5) <85/5
 (x + 5) <17
 Step 2:
 Pass the 5 inside the parenthesis to subtract:
 (x + 5) <17
 x <17-5
 x <12
 The answer is:
 x <12
 equivalently:
 x: (-inf, 12)
  
 x <12 
 x: (-inf, 12)

The answer is 3. parallelogram
