Part A
9x^2 + 24x + 16 = (3x + 4)(3x + 4)length of each side = 3x + 4 units.
Part B:
16x^2 - 25y^2= (4x + 5y )( 4x - 5y)
length = 4x + 5y and width = 4x - 5y
Answer:

Step-by-step explanation:
The imaginary unit is
.
Now 63 itself is not a perfect square but 63 does contain a factor that is.
63=9×7 and 9 is a perfect square.
So
.

there are 6 1/6 per hour
