Hello from MrBillDoesMath!
Answer:
(3b -a) / ( 1 + b^2)
Discussion:
My best guess is that we are trying to simply this fraction:
( 3 - a/b) / ( (1/b) + b) = => multiply num. and denom. by "b"
(3b - a) / ( (1/b)*b + b*b) =
(3b -a) / ( 1 + b^2)
Thank you,
MrB
Answer:
(x+1)(x+20)
Step-by-step explanation:
1) find two factors of 20 that sum up to 21.
2) 1 and 20 are two facts of 20 that sum up to 21.
Answer:
See the first attachment. The numbers indicate the order 1=least, 5=greatest.
Step-by-step explanation:
This is a calculator exercise. Put the numbers in your calculator and have it tell you the result. Don't forget that (ab)/(cd) = ab/c/d if you don't use parentheses.
See the 2nd and 3rd attachments for the values of the expressions.
___
You can estimate values as follows (top to bottom):
1. 4·9·10^(8-5) ≈ 36·10^3
2. 7·8·10^(5-2) ≈ 56·10^3
3. (7·9)/(8·4)·10^(5-7+2+3) ≈ 2·10^3
4. (8·10)/(8·6)·10^(4+1-11+8) ≈ 1.7·10^2
5. (2·6)/(3·5)·10^(4+3+2-2) ≈ 0.8·10^7
These are crude estimates, but sufficiently close to put the numbers in order as required.
