(-x-1)(x-1)(x^2+6)
distribute from there i think?
math papa website can help with this... im not that good at math

DNE
do not exist
Step-by-step explanation:
There is no common factor at all
8 equals 2,4,1,8
11 just equals 1,11
Answer:
The expression that represents the number of days until only 10% remains is T((d) 10 %) =100×.
Step-by-step explanation:
The equation for half life is of the form
A = A₀×.........................................................................(1)
Where
A = Final amount
A₀ = Initial amount
t = Time
h = Half life
For the equation T(d) = 100×2⁽⁻²⁾....................................(2)
We have by comparison with the equation for half life
2 ≡ and and the equation (2) can be written as
Percentage remaining after 2 half lives is
×100=100×
However if the half life of Technetium-99m is 6 hours then we have for one day
×100=100×
Therefore an expression that represents the number of days until only 10% remains is
×100=100× = 10 %
=
= ㏑ = ㏑()
= ×㏑ = ㏑()
= = 3.322
Therefore the expression for the number of days 10 % of Technetium-99m will be remaining is
T((d) 10 %) =100×
Distributive property of multiplication has two expressions:
1.
2.
If you use these formulas from the left side to the right side, you should see for the sign in the brackets: "+" - use addition, "-" - use subtraction. If you use these formulas from the right side to the left side, you should also take into account sign between and : for "+" - use addition in brackets and for "-" - use subtraction in brackets.
Answer:
3^-x= 3^ 3x + 6
Step-by-step explanation:
match bases
remeber if a^b=a^c where a=a then b=c
remember
(x^m)^n=x^(mn)
1/(x^m)=x^-m
base of 3
(1/3)^x=(3^-1)^x=3^(-x)
27^(x+2)=(3^3)^(x+2)=3^(3x+6)
3^(-x)=3^(3x+6)
-x=3x+6
0=4x+6
-6=4x
-3/2=x
