Question

Which expression is equivalent to 7(a + 2) when a = 6?

a) 7(6)
b) 9(6)
c) 7(6) + 2
d) 7(6) + 14

Answer 1

When substituting a = 6 into the expression 7(a + 2), the equivalent expression is 7(6) which simplifies to 56. Option (a) is the correct answer.

Step-by-step explanation:

The question asks which expression is equivalent to 7(a + 2) given that a = 6. To find the equivalent expression, substitute the value of a into the equation:

7(a + 2) = 7(6 + 2) = 7(8)

Now, multiply 7 by 8 to get the simplified result.

7(8) = 56

Therefore, the equivalent expression, when a = 6, is 7(6) which corresponds to option (a).
