To find the value that comes in place of the question mark (?), we can set up the equation and solve it step-by-step.
The given equation is:
Let the unknown value represented by the question mark be . The equation becomes:
Step 1: Simplify the square root
First, find the square root of 225. Since , we have:
Substitute this back into the equation:
Step 2: Solve the operation inside the parentheses
Multiply 4 by 15:
Now update the equation:
Step 3: Multiply the terms on the left-hand side
Multiply 60 by 3:
Step 4: Isolate the variable
Subtract 120 from both sides of the equation to find the value of :
Therefore, the value that will come in place of the question mark is 60.
