look at the very end
To solve the expression 2s - 4r^2 given that r = 1 and s = 5, we need to substitute the given values for r and s into the expression and perform the calculations.
Step 1: Replace r with 1 and s with 5 in the expression.
2(5) - 4(1^2)
Step 2: Simplify the calculation inside the parentheses.
2(5) - 4(1)
Step 3: Multiply.
10 - 4(1)
Step 4: Simplify further.
10 - 4
Step 5: Perform the subtraction.
6
Therefore, when r = 1 and s = 5, the value of the expression 2s - 4r^2 is 6.
