4(x - 3) - 2(x - 1) > 0
4x - 12 - 2x + 2 > 0
2x - 10 > 0 |add 10 to both sides
2x > 10 |divide both sides by 2
x > 10 ⇒ x ∈ (10; ∞)

Answer:
The answer is 30ft.
Step-by-step explanation:
To find the surface area of a rectangle, we use the formula L(2) + W(2) + H(2)
Our length is 7ft
Our Width 2ft
Our height is 6ft
Let's plug our numbers into our equation:
7(2) + 2(2) +6(2)
= 14 + 4 + 12
=30 ft.

Explanation:
The first step is to determine the total of oil that was used for the 5 batches. To find this, you just need to multiply the amount of oil used for one batch by the total batches.
1 cup of oil per batch x 5 batches = 5 cups of oil
This means, in the 5 batches the oil Dinesh used was 5 cups of oil. Additionally, you know the total of cups in the bottle of oil is 12 cups, and these 12 cups or total costs $36. Now to find what is the cost of the 5 cups use the rule of three and cross multiplication.
12 cups of oil = $36 1. Write the values
5 cups of oil = x
12 x = 180 2. Cross multiply this means 36x 5 and 12 multipy by x
x = 180 ÷ 12 3. Solve the equation
x= 15 - Cost for 5 cups used in the batches
