Answer:
Estimation is a mental process of coming up with an answer that is relatively close, to allow decisions to be made. The types of estimation are quantity, computation and measurement.
An estimation strategy is simply coming up with a good estimate based on evidence and already known facts. Coming to a conclusion as close to the real answer as you can. It can also be called an educated guess.
Answer:
LCM = 20
Step-by-step explanation:
You need to make everything into 20. Luckily, 4X5 is 20 and vise versa.
Answer:
1) 2(t - 7)(t + 1)
2) $32,000
Step-by-step explanation:
v(t) = 2t² - 12t - 14
v(t) = 2(t² - 6t - 7) = 2(t - 7)(t + 1)
x = -b/2a = 6/2 = 3
y = 2(3)² - 12(3) - 14 = -32
(3, -32) means at 3 months, -32 thousand dollars
Answer:
Step-by-step explanation:
It is true that for any given odd integer, square of that integer will also be odd.
i.e if 
is and odd integer then 
is also odd.
In the given proof the expansion for 
is incorrect.
By definition we know,
∴ 
Now, we know 
and 
will be even values
∴
will be odd
hence will be odd, which means will be odd.
