(5x - 3y)(4x - 2y)
Simply the polynomial

=20x2−22xy+6y2

Step-by-step explanation:

(5x−3y)(4x−2y)

=(5x+−3y)(4x+−2y)

=(5x)(4x)+(5x)(−2y)+(−3y)(4x)+(−3y)(−2y)

=20x2−10xy−12xy+6y2

=20x2−22xy+6y2

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
