The top row contains the product of
with each term of the expressions
and bottom row contains the product of -1 with each term of expression
.
The final result will be the sum of terms of both rows as shown below:
So the correct answer is option D
SOLUTION:
Highest common factor of 16 and 20 which is also below 9 is 4.
HCF of 16 and 20 = 4
Hope this helps! :)
Have a lovely day! <3
Answer:Take as an example
Step-by-step explanation:
7,203 x 6,892. If I want to know that exactly, then I reach for Mathematica (or if I absolutely have to, I reach for pencil and paper to apply multiplication in columns). But often I just need a rough answer, so I mentally convert this to 7,000 x 7,000 = 7 x 7 x 1,000 x 1,000 = 49,000,000. More formally I am converting the numbers the nearest approximation of the form k x 10n where k ∈ {the set of numbers for which I know times tables}. Then I use the times tables on the remaining significant digits and implicitly use the 10 times table to get the magnitude right. In this case the real answer is:
Ok I got 32.995 I’m not sure what place you need to round to so I kept that throughout my solving process. I’m not too sure if this is right but here is the work that I did in the picture. I didn’t show the distance formula as I used an online calculator lol.
