evaluate the following expression when x = 5: 8(2x+6)
To evaluate the expression 8(2x+6) when x = 5, we substitute the value of x into the expression:
8(2x+6) = 8(2(5)+6)
= 8(10+6)
= 8(16)
= 128
Therefore, when x = 5, the expression 8(2x+6) equals 128.
To evaluate the expression 8(2x + 6) when x = 5, follow these steps:
Step 1: Substitute the value of x into the expression:
8(2 * 5 + 6)
Step 2: Simplify the expression within the parentheses:
8(10 + 6)
Step 3: Perform the addition within the parentheses:
8(16)
Step 4: Multiply 8 by 16:
128
Therefore, when x = 5, the value of the expression 8(2x + 6) is 128.
To evaluate the expression 8(2x+6) when x = 5, you need to substitute the value of x into the expression and perform the computation accordingly.
First, let's substitute x = 5 into the expression:
8(2(5)+6) = 8(10+6)
Next, simplify the expression inside the parentheses:
8(16)
Finally, multiply 8 by 16 to get the final result:
8 * 16 = 128
Therefore, when x = 5, the expression 8(2x+6) evaluates to 128.
