895 because 89.5 divided by 0.1 is 895
P (smaller) : P (larger) = 5 : 8
P (larger) = 72 in
P s : 72 = 5 : 8
8 P s = 72 * 5
8 P s = 360
P s = 360 : 8
P s = 45 in
Answer:
The perimeter of the smaller rectangle is 45 inches.
Answer:
Im gonna guess 6
Step-by-step explanation:
Factor:
9x^2 - 64
= (3x)^2 - 8^2
= (3x + 8)(3x - 8)
If you want to solve it, let the equation equal zero
(3x + 8)(3x - 8) = 0
3x + 8 = 0 ; x = -8/3
3x - 8 = 0 ; x = 8/3
Solutions: x = -8/3 and x = 8/3
