Yis between x and z. find the length of yz if
xy = 3a - 4, yz = 6a + 2, and xz = 5a + 22.
(line segments and distance)

Step-by-step explanation:

we know that

If Y is between X and Z

then

substitute the given values and solve for a

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
