Question

The lengths of a diagonal of a square are 3x + 1 and x + 13 . Find the value of x.

Answer 1

Answer:

x = 6

Step-by-step explanation:

The diagonals of square are equal.

Hence,

3x + 1 = x + 13

3x - x = 13 - 1

2x = 12

Answer 2

Answer:

X = 6

Step-by-step explanation:

The diagonals of the square are equal.

Therefore,

» 3x + 1 = x + 13

» 3x - x = 13 - 1

» 2x = 12

» X = 6

And , the two diagnols will be also :-

i) 3x + 1 = 3 × 6 + 1 = 18 + 1 = 19

ii) x + 13 = 6 + 13 = 19
