Question

Evaluate the variable expression when a=4,b=5, and c=-5. (b-a)²+2c -11 0 -9 -4

Answer 1

To evaluate the expression (b-a)²+2c -11, substitute the values a = 4, b = 5, and c = -5. The result is -20.

Step-by-step explanation:

To evaluate the variable expression (b-a)²+2c -11, we substitute the values a = 4, b = 5, and c = -5 into the expression.

First, we calculate (b-a)² = (5-4)² = 1² = 1.

Next, we plug in the value of c, which gives us 2c = 2(-5) = -10.

Finally, we add all the computed values together to get (b-a)²+2c -11 = 1 + (-10) -11 = -20.
