Perimeter of one triangle is 5 8 of the perimeter of a similar triangle. The difference of the lengths of two corresponding side
Makovka662 [10]

Answer:

15 m and 24 m

Step-by-step explanation:

Let x represent the length of the longer side. Then 5/8x is the shorter side and the difference is x -5/8x = 3/8x.

You say the difference is 9 m, so ...

... 3/8x = 9 m

... x = (8/3)(9 m) = 24 m . . . . longer side

and the shorter side is (5/8)(24 m) = 15 m. . . . . shorter side

IF YOU GET THIS ALL RIGHT ILL GIVE AWAY 99 POINTS!!!!!
Dovator [93]
Simplifying -2x + -4y = 9 Solving -2x + -4y = 9 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4y' to each side of the equation. -2x + -4y + 4y = 9 + 4y Combine like terms: -4y + 4y = 0 -2x + 0 = 9 + 4y -2x = 9 + 4y Divide each side by '-2'. x = -4.5 + -2y Simplifying x = -4.5 + -2y<span>13/18
