Answer:
Aaron needs <u>2 more rolls</u> to complete the path.
Step-by-step explanation:
Given:
Total rolls Aaron has = 4
Part of path covered by using
of a roll = 
So, in order to find the number of rolls required to cover the complete path is given using the unitary method.
Rolls used for
of a path = 
Therefore, rolls used to cover the whole path is given by dividing the rolls used for one-eighth of the path and the path covered. This gives,





Now, rolls required to complete the path is 6. But Aaron has only 4 rolls.
So, he will need 6 - 4 = 2 rolls more to complete the path.
True, because the triangle is symmetrical
Hope this helps :)
area=legnth times width
we notice this is a special case
(a+b)(a-b)=a^2-b^2
area=(a+3b)(a-3b)=a^2-9b^2
area=a^2-9b^2
X = y + 5
-y + x - x = y - y + x + 5
-y = x + 5
y = x - 5
