Evaluate the expression for the for the given value of the variable.....................
4(x-4; x = 7
Can someone help please, I have been having trouble with this problem for sometime now.
substitute 7 in x spot
so 4 (7-4)=4(3)=12
Sure! To evaluate the expression 4(x - 4) for the given value of the variable x = 7, you need to substitute the value of x into the expression and perform the calculations.
Let's begin by substituting x = 7 into the expression:
4(7 - 4)
Next, simplify the expression inside the parentheses:
4(3)
Now, multiply the 4 outside the parentheses by 3:
4 * 3 = 12
Therefore, the value of the expression 4(x - 4) when x = 7 is 12.
