Please help I don't understand this

Answer 1

26

Explanation:

4(5)+6=26

Answer 2

x = 5 , ST = 26

Explanation:

since S lies between R and T , then

RT = RS + ST ( substitute values )

8x = 14 + 4x + 6 ( simplify right side )

8x = 4x + 20 ( subtract 4x from both sides )

8x - 4x = 4x - 4x + 20 ( simplify both sides )

4x = 20 ( divide both sides by 4 )

`(4)/(4)` x =
`(20)/(4)` , that is

x = 5

Then

ST = 4x + 6 = 4(5) + 6 = 20 + 6 = 26
