Answer:
The answer is 54.
Step-by-step explanation:
54 divided by 2 will give you 27.
54 divided by 9 will give you 6.
a perfect square trinomial, (x + y)² = x² + 2xy + y²
so, if we have the x of the bx, what is left is the b
the expression would have to be (x + 7)², since we have the 49 and the x²
so, what's left: x² + 14x + 49,
b = 14
