Answer:
(x-1)²=8.
Step-by-step explanation:
1) if the length before decreasing is 'x', then after decreasing it is x-1;
2) then the area is (x-1)²=8.
PS. the length before decreasing is 1+2√2.
Answer:
B. 8 x 10^3
Step-by-step explanation:
1.6 x 10^5 / 0.2 x 10^2
= 160 000 / 20
= 8 000
You can write this as 8 x 10^3
Answer: I do not have expertise on this so I won't answer the exact problem but this sounds like exponential decay, where you have the decay rate. I know that the formula for exponential decay is: y = a(1 - r)^x
I'm sorry if this does not help much I don't have expertise on this. Sorry again.
