Answer:
n ≥ 5
Step-by-step explanation:
The money that Janie earns (E) must be greater than or equal to the cost (c) of the CD.
In symbols,
E ≥ c
2n + 3 ≥ 13 Subtract 2 from each side
2n ≥ 10 Divide each side by 2
n ≥ 5
Janie must do five or more chores to buy the CD.
Answer:
2(x + y)² - 9( x + y ) -5 = 0
⇒2(x + y)² - 10 (x+y) +1(x+y) -5 = 0
⇒2(x+y)(x + y - 5 ) + 1(x + y -5 ) = 0
taking (x + y -5 ) common ,
⇒(x + y -5 )[2(x + y) + 1] =0
⇒(x + y -5)(2x + 2y +1) =0
