Answer:
19
Step-by-step explanation:
simple, since all sides of a square are equal, we have that;
6x - 2= 4x + 5
collect like terms
6x - 4x = 5 + 2
2x = 7
dividing throughout by 2
x = 7/2
x = 3.5
since x= 3.5 or 7/2, we can now find the length of one side of the square by simply substituting value of x for x.
6x - 2
6(7/2) - 2
21 - 2
length of a side of the square= 19
OR
4x + 5
4(7/2) + 5
14 + 5
length of a side of the square= 19
