1.2 meters = 120 centimeters
amount of increase = 120-80 = 40 centimeters
40 ÷ 80 = 0.5 = 50%
There was a 50% increase.

Answer:
a: 3
b. 6973568802
Step-by-step explanation:
a₁ = 6 , r = 3 , a₂₀ =?
Result:
a₂₀ = 6973568802
Explanation:
To find a₂₀ we use the formula
aₙ = a₁ · r
^ⁿ⁻¹
In this example we have a₁ = 6 , r = 3 , n = 20. After substituting these values to above
formula, we obtain:
aₙ = a₁ · r
^ⁿ⁻¹
a₂₀ = 6 · 3
^²⁰⁻¹
a₂₀ = 6 · 1162261467
a₂₀ = 6973568802
 
        
             
        
        
        
For this case we must find the value of the variable "p" of the following equation:

We apply distributive property on the left side of the equation taking into account that  and
  and  :
:

We add similar terms:

We subtract  from both sides of the equation:
  from both sides of the equation:

We subtract 8 from both sides of the equation:

We divide by -6 on both sides of the equation:
