0 = impossibe
1 = most likely/ certain
Find the area of the whole rectangle and find the area of the not shaded part and then subtract them to find the are of the shaded part.
Area of whole: 10 * 6 = 60 cm²
Area of non shaded: 6 * 2 = 12 cm²
Area of shaded part:
60 - 12 = 48 cm²
Hope this helps :)

Step-by-step explanation:
Given
--- Flow rate of the shower
--- Drain rate of the bathtub
-- Bathtub size
Required
Determine the maximum time of shower
First, we calculate the rate at which the bathtub fills.
The maximum time of shower is:
Answer:
B
Step-by-step explanation:
Given the 2 equations
4x + 3y = 16 → (1)
7x + 6y = 31 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the term in y
- 8x - 6y = - 32 → (3)
Add (2) and (3) term by term
- x = - 1 ( multiply both sides by - 1 )
x = 1
Substitute x = 1 in either of the 2 equations and solve for y
Substituting in (1)
4(1) + 3y = 16
4 + 3y = 16 ( subtract 4 from both sides )
3y = 12 ( divide both sides by 3 )
y = 4
Solution is (1, 4 ) → B
