The legs of an isosceles triangle have lengths 2x+3 and -X+9 The base has length . 3x+6 What is the length of the base? A. 2
B. 7
C. 12
D. can't be determined

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
