I think so. But, the only way you can simplify is is if you add the like terms, in this case, -4x and -11x. #1 will simplify to -15x=36. you cannot simplify the other one any further. <span />

Need help with #12<br> Please help
Korolek [52]

Step-by-step explanation:

If the figure is triangle then,

Let PR be x

So,

PQ+QR+PR= 180 (Sum of all the angles of the triangle)

Therefore,

6x+25+16-3x+x=180

4x+36=180

4x= 180/36

x= 144/4

X= 36

NOW,

PQ= 6x+25

= 6(36)+25

= 216+25 = 241= PQ.

QR = 16-3x

= 16-3(36)

= 16-108

= -92

PR = 36

hope it helps
