6a + 42
6(8) + 42
48 + 42 = 90
To find the value of 6(a+7) when a=8, you need to substitute the value of a into the given expression and perform the necessary calculations.
Start by replacing the variable 'a' with the value of 8:
6(8+7)
Next, simplify the expression inside the parentheses:
6(15)
Now, multiply 6 by 15:
90
Therefore, when a=8, 6(a+7) is equal to 90.
