The legs of an isosceles triangle have lengths x + 1 and -x + 7 . the base has length 3x - 3. what is the length of the base? a 4 b 6 c 3

The base is 6.

In order to find this, we can set the legs equal to each other since legs have the same length in an isosceles triangle.

x + 1 = -x + 7

2x + 1 = 7

2x = 6

x = 3

Now that we have the value for x, we can plug into the equation to get the value for the base.

3x - 3 = base

3(3) - 3 = base

9 - 3 = base

6 = base

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
