Answer:
the one on the far right
Step-by-step explanation:
10 is not to the power of something in that equation
The given trinomial can be factored using the factorization method.
x² -6x +9
= x² -3x -3x +9
= x(x-3) - 3(x-3)
= (x-3)(x-3)
Thus, (x-3)(x-3) is the factored form of the polynomial.
So the correct answer is option D
X could equal 12 and y could equal 3
Answer:
5/8 =x
Step-by-step explanation:
9=8/5(x+5)
Multiply each side by 5
5* 9=5*8/5(x+5)
45 = 8(x+5)
Distribute
45 = 8x+40
Subtract 40 from each side
45-40 = 8x+40-40
5 = 8x
Divide each side by 8
5/8 = 8x/8
5/8 =x
Answer:
25.9 years
Step-by-step explanation:
The half life of an isotope is related to the actual amounts by the equation:
N = Ni*(1/2)^(t/HL)
where N and Ni are the final and initial (Ni) amounts, t is the time (in years for this problem) and HL is the half-life, in years.
In this problem, we can write:
100 = 360*(1/2)^(x/14)
I'll reduce this to:
1 = 3.6*(1/2)^(x/14)
This can be solved by taking the log of both sides.
x = 25.87 or 25.9 years
