D^2 = (x2-x1)^2 + (y2-y1)^2
D =sqrt((10+5)^2 + (10-2)^2)
D P SQRT(15^2 + 8^2)
D = sqrt(225 +64)
D= sqrt(289)
D = 17
The distance is 17
The number is 'n'.
Five times the number is 5n .
Nine more than that is 5n + 9 .
Step 3: 4x+8=4
Step 4: 4x=4-8 ⇒4x=-4
Answer: Step 4: 4x=-4
Step 5: x=-4/4=1
Answer:
C
