If AC equals 2x + 13 and DB equals 4x - 1 what is DB
4x-1
To narrow that down to a number, you need to provide some relationship between AC and DB.
If ABCD is a square, then of course
2x+13 = 4x-1
and just find x.
To find the value of DB, we need to substitute the given value of x in the expression for DB.
It's given that AC = 2x + 13 and DB = 4x - 1.
Let's assume x = 5. Now, we can substitute this value of x into the expression for DB.
DB = 4(5) - 1
= 20 - 1
= 19
Therefore, when x = 5, DB = 19.
