If x is 4 then 34.5x evaluates to 34.5 times 4 = 138
The answer is x = 5. There is nothing to evaluate there!
Evaluate the expression below when x = 2.3x2-2x+4

Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
X = 7 9x - 2x = 49
5gz = 5 x 3 x 4 = 60
5gz = 5 x 3 x 4 = 60
The answer is x = 5. There is nothing to evaluate there!
Evaluate the expression below when x = 2.3x2-2x+4
There is no box below!
To evaluate the expression ( x^2 + 6x - 4 ), you need to substitute a specific value for ( x ) and then calculate the result. For example, if ( x = 2 ), you would calculate ( 2^2 + 6(2) - 4 ), which simplifies to ( 4 + 12 - 4 = 12 ). This process can be repeated for any value of ( x ) to find the corresponding output of the expression.

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
It is x*x + y*y*y*y
Evaluating a function called f(x) at f(4) basically means you set x = 4 in f(x) and solve. In other words, you solve the expression for x = 4. In this case: f(x) = 3x + 7f(4) = 3(4) + 7f(4) = 12 + 7f(4) = 19So, if you evaluate this function for f(4), you get 19.
The expression "6 plus 4(x - y)" simplifies to ( 6 + 4x - 4y ). If ( x ) and ( y ) are variables, this represents a linear expression in terms of ( x ) and ( y ). Without additional context or values for ( x ) and ( y ), we cannot evaluate it further.
