69 people got the free admission and that after that 154 more people came, so 20 people more and after than someone goes in for free!
Answer:
Step-by-step explanation:
A=2B
AreaA= Area of a rectangle=Base* height = base (12-x)*height(4) = 48-4x
AreaB = Area of rectangle=base(x) *Height(x) =x^2
Since A=2B
48-4x =2x^2
Divide both sides of the equation by 2
24-2x=x^2
Put everything all on one side
X^2-2x-24=0
(x+4)(x-6)=0
X=-4 and x=6
Only x makes sense since it’s not negative or else your base or one of your sides would be negative
So x=6
Multiply both the numerator and the denominator by the same number and you'll get an equivalent fraction. For example, 3/5 times 2/2 equals 6/10, which is an equivalent fraction to 3/5. Multiply both by 8, and you have 24/40, which is also equivalent to 3/5. I hope this helped you tremendously! <span />
That would be 12x^3-16x^2+3x-4
