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

Step-by-step explanation:
T in time in minutes would be 60 min every hour 35/.6 minutes
7,134 + d = 10,000
Subtract 7,134 from each side:
d = 10,000 - 7,134
d = 2,866
