Lauren needs to sell 6 more tickets to reach her goal. 30- (12x2) 12x2=24 30-24=6
Answer:x=-5 and x=3
Step-by-step explanation:
log(x^2-15)=log(2x)
Cancel log at both sides we get
x^2-15=2x
Collect like terms
x^2-2x-15=0
x^2-3x+5x-15=0
x(x-3)+5(x-3)=0
(x+5)(x-3)=0
x+5=0 x-3=0
x=-5 x=3
73℅ of 58
= (73/100) × 58
= (73×58)/100
= 4234/100
= 42.34
