If p(x) = 2x - 5 and r(x) = 3x + 4, calculate (pr)(x). A 6x2 - 7x - 20
B 6x² +7X-20
C 5x - 1
D 6x2 - 20

A) 6 x² - 7x - 20

Step-by-step explanation:

Explanation:-

Given p(x) = 2 x-5 and r (x) = 3 x +4

(pr)(x) = p(x) r(x)

         = (2x -5)( 3 x +4)

        = 2x(3x +4) -5( 3x +4)

       = 6 x² + 8x - 15 x - 20

       =  6 x² - 7x - 20

(pr)(x) = 6 x² - 7x - 20

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

definitely a. the others have almost all data points on one side of the line.
