Hi! Your answer is 13.
All you have to do is divide 52 by 4. When you do this, you will find how many laps they walked per hour.
(They walked 52 laps in 4 hours)
52 / 4 = 13
They walked 13 laps in one hour.
Hope this helped!
Answer:
Step-by-step explanation:
Given:
5/2(6x - 7) + 4/3(2 + 9x)
Rewrite:
Distribute by multiplying:
Distribute by multiplying again:
Combine like terms:
The given expression, simplified, is;
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
