Since it says that T is the midpoint that means it equal divided the line. So,
X+3 must equal 4x
X+3 =4x
Subtract x on both sides
3=3x
Divide 3 on both sides
1=x
Plug in x into equation
4(1) =4

TU =4

Answer:

4

Step-by-step explanation:

Here we know that T is the midpoint of SU.

Therefore, we know ST and TU are equal.

Setting their values equal, we get:
x+3 = 4x

Then we isolate x by subracting x from both sides:

3=3x

Finally we divide by 3:

1=x

Now we can solve for TU:

4x= 4(1) = 4
