If p is the midpoint of st, sp = x + 4, and st = 4x, determine the length of st

ST = 16.

Step-by-step explanation:

Given  : P is the midpoint of ST, SP = x + 4, and ST = 4x,

To find :  Determine the length of ST.

Solution : We have given P is mid point of ST.

It mean P divide the ST in to two equal parts .

So, SP = PT .

We can say

ST  = 2 SP .

Plug the given values SP = x + 4, and ST = 4x,

4x = 2 ( x +4).

4x = 2x + 8.

On subtracting both sides by 2x

4x -2x = 8.

2x = 8

On dividing both sides by 2

x = 4.

ST = 4 * 4 = 16.

Therefore, ST = 16.

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
