Step-by-step explanation:
the writing and spacing of the problem description is difficult to understand.
but there is no mystery. look at the examples.
all of them
3×5 = 15 = 16 - 1 = 4² - 1
4×6 = 24 = 25 - 1 = 5² - 1
5×7 = 35 = 36 - 1 = 6² - 1
6×8 = 48 = 49 - 1 = 7² - 1
7×9 = 63 = 64 - 1 = 8² - 1
8×10 = 80 = 81 - 1 = 9² - 1
so, what does this look like ?
(x-1)×(x+1) is always equal to (x² - 1)

Answer:
c
Step-by-step explanation:
How to remember which is which? Well, alphabetically they are:
Complementary add to 90°
Supplementary add to 180°
You can also think:
"C" of Complementary is for "Corner" right angle(a Right Angle), and
"S" of Supplementary is for "Straight" (180° is a straight line)
Or you can think:
when you are right you get a compliment (sounds like complement)
"supplement" (like a vitamin supplement) is something extra, so is bigger
The answer is 20 prints.
Explanation:
The total cost is $11. Joseph paid $8 for the SUBSCRIPTION (NOT PRINTS) already, so we take away the 8 from 11, equaling in $3 left.
The question is asking for the amount of prints. Now that we only have 3 dollars left, we just divide that by the cost of each print (0.15) to see how many prints can go into that cost.
3 divided by 0.15 is 20. So, Joseph purchased 20 prints.
