1.
Given that R is between A and X on a segment, draw a picture and write an equation
using the Segment Addition Postulate. Then find AR and RX if AR = 5x - 15,
RX = 3x + 1, and AX = 58.
2.
Given that R is the midpoint of segment AX, write an equation if AR = 5x - 15 and
RX = 3x + 1. Then find AR, RX, and AX.
3.
The endpoints of a segment are (-3,4) and (5, -8). Find the length of the segment to
the nearest tenth and then find the coordinates of the midpoint.

Ответ:
i think your question was suppose to have bracket
as for me I included brackets in my calculations
Step-by-step explanation:
(9x+5)(14x-4)
9x(14x-4)+5(14x-4)
126x²-36x+70x-20
126x²+34x-20
