Evaluate the following expression for x = 4:
x2 + 3x - ( x + 5 ) =
2
Substituting x = 4 into the expression, we have:
4^2 + 3(4) - (4 + 5) = 16 + 12 - 9 = 19
So, the evaluated expression is 19.
To evaluate the expression for x = 4, we substitute x = 4 into the given expression:
x^2 + 3x - (x + 5) = 2
Replacing x with 4:
4^2 + 3(4) - (4 + 5) = 2
Calculating each part:
16 + 12 - 9 = 2
Adding and subtracting:
28 - 9 = 2
Simplifying:
19 = 2
However, 19 does not equal 2. So, it seems there might be an error in the expression or the given values.
