Answer:
10x-22
Step-by-step explanation:
((x+2)(x-1))-((x-4)(x-5))
(x^2-x-2)-(x^2-9x+20)
x^2 + x - 2
+ (-x^2+9x-20)
_______________
10x-22
x=8
Step-by-step explanation:
move the +2 to the right side so it can be subtracted by the 5 to get 3. after that you square both sides of the equation to get rid of the square root symbol. then move the -7 to the right side and add it with 9. then you'll have 2x=16. then divide both sides by 2 to get x by its self and you are left with x =8
Answer:
25.48 days
Step-by-step explanation:
For a radioactive substance, the Amount of the substance remaining A(t) is modeled by the equation

where

In the given problem:
Half Life of the Radioactive Isotope = 8
Initial Amount,
=100%=1
A(t)=11% =0.11
Therefore substituting in the model above:

The farmer need to wait for 25.48 days
