Answer:
-36x² - 8x - 8
Step-by-step explanation:
Distribute 6x and -8 through the parenthesis:
-48x + -36x² - 8 + 40x
Collect the like terms:
-8x - 36x² - 8
Use the commutative property to reorder the terms:
-36x² - 8x - 8
One endpoint at 1,3 and the midpoint at 3,5
Your answer would be to as two to each the x and y of the midpoint. so 5,7
Since one page cost $1.25 to print take the cost of per page $1.25 times the number of pages to be printed, in this case eight. $1.25 x 8 = $10.00
Remember there is still a $3.50 added to the cost of the pages printed; thus you have $10.00 + $3.50 = $13.50 which is the total charge.
Using Euclid's algorithm, the first number you check is their difference:
60 - 48 = 12
Since 12 divides both numbers evenly, that is your GCF.
_____
If the difference does not divide both numbers evenly, you can repeat the procedure with the difference and the remainder from dividing the smallest of the other numbers by the difference. For example, ...
GCF(60, 44) = GCF(44 mod 16, 16) = GCF(12, 16) = 4
Percent decrease : (original number - new number) / original number)...x 100
(13.00 - 7.50) / 13.00 = 5.5/13 = 0.42....x 100 = 42% decrease
