Answer:
(4x -2y)-( 2x-6y) = 2x-(-4y)
Step-by-step explanation:
only the same sign can be together. so you take the x first 4-2 which is 2x then you take the y signs 2-6 which would be -4 the full equation becomes 2x-(-4)
To solve this, you can set up an equation. Make the length of the shortest side x, so the 2 sides double the length will equal 2x. Since they all equal the perimeter of 36, do x + 2x + 2x =36. These values all represent the sides(2 longer, one short). Combine like terms to get 5x=36 then divide by 5 to find the value of x. x=7.2in meaning the shorter side is 7.2 inches while the longer sides are both 14.4 inches each since they are double in size.
