First, group them in 2's (2 numbers per group)
and see which ones have the factors of each other
you want to group 12x^3 with 3x because 3 is a factor of 12
then you want to group -20x^2 and -5 together becuase 5 is a factor of 20 so
(12x^3+3x)+(-20x^2-5)
undistribute
(3x)(4x^2+1)+(-5)(4x^2+1)
revese distribute (ab+ac=a(b+c))
(3x-5)(4x^2+1)
I believe the answer is y ≤ -3x + 5.
I have not learned inequalities yet so if I am wrong, then :/

Answer:
x = 3
Step-by-step explanation:
It is convenient to remember the ratios of side lengths of these "special triangles."
The side ratios of ΔABC are 1 : 1 : √2, so BC = AC/√2 = 6.
The side ratios of ΔBCD are 1 : √3 : 2, so BD = BC/2 = 6/2 = 3.
The value of x is 3.
D. Use FOIL and guess and check to factor the equation
They decrease the workload by decreasing the amount of energy necessary to lift said object.
