Answer:

SU = 36

Step-by-step explanation:

T is the mid point so the distance of ST and TU is the same. Since ST and TU are the same, 7x + 4 = 10x - 2.

Solve for x

7x + 4 = 10x - 2

7x - 10x = - 2 - 4

-3x = -6

x = 2.

Find SU

SU = ST + TU

= (7x + 4) + (10x - 2)

substitute the value for x into the equation (x=2)

[7(2) + 4] + [10(2) - 2] = 36

I hope this helps :)
