4. The legs of an isosceles triangle have lengths 3x + 3 and -x + 15. The base has length 2x - 3. What is the length of the base?

3

Step-by-step explanation:

The legs are congruent which means:

3x + 3 = -x + 15

4x = 12

x = 3 which means the base is 2x - 3 = 2(3) - 3 = 3.

Step-by-step explanation:

here x= 3

therefore substitute x=3 in base lenght

ie 2x -3 = 6-3 =3

therefore base length = 3
