Point T is on line segment S U . Given T U = 4 x + 1 , S U = 8 and S T = 3 x , determine the numerical length of T U ‾ .

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

he kicked it up? is this the answer ?

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
