Use the diagram below to answer question, if QR = 6x + 1, PR = 14x – 13, and 1 point PQ = 5x – 2, find PR. (Utilice el diagrama siguiente para responder a la
pregunta, si, QR = 6x + 1, PR = 14x – 13, y PQ = 5x - 2, encuentre PR.)

43 units

Step-by-step explanation:

Given the data, QR = 6x + 1, PR = 14x – 13, and  PQ = 5x - 2, it can be inferred that PQ+QR = PR

Substitute the given functions

5x - 2+6x + 1 =  14x – 13

collect like terms

5x+6x-2+1 =  14x – 13

11x-1 =  14x – 13

11x-14x = -13+1

-3x = -12

Divide both sides by -3

-3x/-3 = -12/-3

x = 4

Substitute x = 4 into PR = 14x – 13;

PR =  14(4) – 13

PR = 56-13

PR = 43

Hence the length of PR is 43 units

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
