Answer:
C
Step-by-step explanation:
The answer is 16x-20. First, you have to distribute 12 and 4 making the equation 12x-48+4x+28. Then, you combine the like terms giving you 16x-20. Hope this helped.

4. ΔRST ≅ ΔTUR <u>SSS rule of congruency</u>
The Side-Side-Side rule of congruency states that if three sides of one triangle are congruent to three sides of another triangle then both triangles are congruent.
Answer:
Step-by-step explanation:
finding PR ( public relations :D , not that PR , the PR on this triangle thingy )
use law of cosines, again
c=sq rt [ a^2+b^2﹣2*a*b*cos(C) ]
where
c=PR
a= 9
b = 22
C = the angle of Q or 180 = 97+24+Q so Q = 180-97-24 = 59°
they tried to trick us.. by not giving us the angle C for the above cosine formula , but we figured out their diabolical plan :D yay super hero math
then
PR = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]
PR = sq rt [ 81 + 484 -203.9550777 ]
( notice that now it is a subtraction sign instead of a plus sign, this time? )
PR = sq rt [361.0449 ]
PR = 19.0011
to the nearest 10th
19.0 :)
