Answer:
20
Step-by-step explanation:
It’s a square. Therefore, the sides have EQUAL length. So, we can set up the two binomials EQUAL to each other like so
6x-1=4x+6
isolate variable, minus 4x both sides and add 1 both sides
2x = 7
x = 7/2
substitute this value into one of the terms to find the length. Only one because they’re equal.
6(7/2)-1=20
