Can anyone me answer this question, i don’t

(i) 17 = x + (3x -5) +(2x +1)

Step-by-step explanation:

(i) The perimeter is the sum of the lengths of the sides. We are given values for each of these quantities, so we can write that sum as ...

... 17 = x + (3x -5) + (2x +1)

This can be simplified to various levels, clear down to a solution.

... 17 = (x +3x +2x) + (-5 +1) . . . . group like terms

... 17 = 6x -4 . . . . . . . . . . . . . . . . combine like terms

... 21 = 6x . . . . . . . add 4

... 21/6 = x = 3.5 . . . . . divide by the coefficient of x

Then, if you're interested in side lengths, they are (in units of cm) ...
