Answer:
(1 , 2), (2 , 4), (3 , 6), and so on
Step-by-step explanation:
10/5 = 2, so each cookie costs $2. So, for every time you increase x by one, you increase y by two.
1 = $2 2 = $4 3 = $6 4 = $8 etc.
hope this helps :)
( 7x + 11 )( 7x- 11 )
Because 7*7 is 49
-11*11= -121
7*11=77
-7*11= -77
77-77=0
so the answer is 49x^2-121
120.
Using the Pythagoras theorem:
(30√2)^2 = x^2 + x^2 where x =length of each side of the square
1800 = 2x^2
x^2 = 900
x = 30.
So the perimeter = 4*30 = 120.
