9x- 7i > 3 (3x-7u)
9x- 7i > 9x-21u
9x-9x-7i>21u
-7i > 21u
L = - W
P = 2L + 2W = 2(L + W) → ( take out common factor of 2)
divide both sides by 2
= L + W
subtract W from both sides
- W = L
Answer: Yes, it is in the blue shaded area
Step-by-step explanation:
(x-y)(x-7)
You can get this by using the splitting method.
The possible outcomes where the red die shows a 3 are: (red, blue) = (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6).
