Answer:
For every 1 liter of bleach there are 9 liters of water in the solution
Step-by-step explanation:
∵ The ratio of bleach to water in a cleaning solution is 2 : 18
- That means for every 2 liters of bleach there is 18 liters of water
∵ There is 1 liter of bleach
- Let us use the ratio method
→ bleach : water
→ 2 : 18
→ 1 : x
- By using cross multiplication
∴ x × 2 = 1 × 18
∴ 2 x = 18
- Divide both sides by 2
∴ x = 9
∵ x represents the number of liters of the water in the solution
∴ The number of liters of the water in the solution is 9
For every 1 liter of bleach there are 9 liters of water in the solution

Step-by-step explanation:
We can get the answer in the following way:
Answer:
(12-7x)
Step-by-step explanation:
144 − 49x²
by observation, we can see that 144 = 12² and 49 = 7²
hence we can rewrite the equation
144 − 49x²
= 12² - 7²x²
= 12² - (7x)²
recall that the expression x² - y² = (x+y)(x-y)
hence,
12² - (7x)²
= (12 + 7x)(12-7x)
(12-7x) appears in the expression above, hence 12 -7x is a factor
