Previously close refers to: a) the last time a stock wil be offered for sale

b the price a stock last sold for at the end of a business day

c time os day the stocks are sold

d the last priceoffered for a group of 10 or more stock

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

step-by-step explanation:
