Answer:
- Initial amount of the material is 67 kg
- Hal-life is 83 hours
<u>The required equation is:</u>
- m(x) = 67 * , where m- remaining amount of the radioactive material, x - number of hours
<u>After 5 hours the material remains:</u>
- m(5) = 67 * = 64.260 (rounded)
Answer:
its might be c, but i think it d
Step-by-step explanation:
Since you've told us that this is an isosceles triangle, we know that the 'legs' have equal length. So we can write
x + 1 = -x + 7
Add 'x' to each side: 2x + 1 = 7
Subtract 1 from each side: 2x = 6
Divide each side by 2 : x = 3
Now, if the length of the base is 3x - 3 ,
that length is
3(3) - 3 = 6 .
Answer:
Option 1
Step-by-step explanation:
12x²+2x-4
2(6x²+x-2)
2(6x²+4x-3x-2)
2(2x(3x+2)-1(3x+2))
2(3x+2)(2x-1)
