The expression 7(6) + 14=56 will be equal to 7(a + 2) at a = 6
What will be the expression equivalent to 7(a + 2) at a = 6?
We have an expression
7(a + 2)
Now at a = 6, its value will be
7 (6 + 2) = 7 × 8 = 56
Now from the given options we can see that
7 (6)=42
9 (6)=54
7 (6) + 2=44
7(6) + 14 = 42 + 14 = 56
Thus the expression 7(6) + 14=56 will be equal to 7(a + 2) at a = 6
