The distance covered by the car is x² + 2x - 15 kilometers at (x - 3) hours. Find the Speed of the car.
sashaice [31]
  • Distance=x^2+2x-15
  • Time=(x-3)h

Speed=Distance/Time

\\ \tt\longmapsto Speed=\dfrac{x^2+2x-15}{x-3}

\\ \tt\longmapsto Speed=(x+5)km/h

#2

  • W be x
  • L be x+4

AtQ

\\ \tt\longmapsto x(x+4)=77

\\ \tt\longmapsto x^2+4x=77

\\ \tt\longmapsto x^2+4x-77=0

\\ \tt\longmapsto x^2+11x-7x-77=0

\\ \tt\longmapsto x(x+11)-7(x+11)=0

\\ \tt\longmapsto x-7(x+11)=0

  • Take it positive

\\ \tt\longmapsto x=7

  • L=x+4=7+4=11units
