Step-by-step explanation:
#12
PQ = 6x + 25
QR = 16 - 3x
PR = 6x + 25 + 16 - 3x
PR = 3x + 41
#1
D = √(-4 - 5)² + (-7 - 2)²
D = √(-9)² + (-9)²
D = √81 + 81
D = √162
D = 9√2
Answer: v < -5 or v < 40
Explanation:
v + 8 < 3
v < 3 - 8
v < -5
OR:
v - 80 < -40
v < -40 + 80
v < 40
I hope this helps you
-9= -4x/5 -2
-7= -4x/5
-35= -4x
x= 35/4
