-2bk2 + 6bk - 2b = -2b(k2 - 3k + 1)
b = 0.2 x 10a = 2aa/(2b) = a/(4a) = 1/4= 25%
Not sure what 2b is but crushed concrete with 1 1/2" rock will cover about 60 square feet. 15 tons ends up being around 12 cubic yards.
5ab(3a - 2b)
Assuming the missing sign is "minus" then you have the difference between two squares. This is solved as (x + y)(x - y). In your example x = 4a and y = 2b so the factorisation is (4a + 2b)(4a - 2b) or more completely: (4)(2a + b)(2a - b).

In an intermediate maths 2B exam, the pass marks are typically determined by the educational board or institution conducting the exam. The pass marks can vary depending on the difficulty level of the exam and the grading system in place. Generally, a passing grade is considered to be around 35-40% of the total marks, which in this case would be out of 75.

A 6B pencil lead will generally mark darker than a 2B pencil lead. The higher the 'B' number, the softer and darker the lead.
There are two terms: 3x, -2b. Yeah, two terms. But where is the equation?
