Step-by-step explanation:
look it is very easy.
use formula of simple interest
Since 1 cm = 10 mm
Then 4 cm = 40 mm
collect the like terms:
Solution: x^2-5xy+4y
P.S
get the photo math app. :)
Hope that helps.
I believe it is 60 inches
Answer: A
Step-by-step explanation:
The sum to infinity of a geometric series is
S (∞ ) = \frac{a}{1-r} ( - 1 < r < 1 )
where a is the first term 8 and r is the common ratio, hence
S(∞ ) = {8}{1-\{1}{2} } = {8}{1}{2} } = 16
