Answer:
5 rolls
Step-by-step explanation:
If the perimeter around the square footage of the ceiling is equal to 12 + 12 + 12 + 12 = 48, even though the number is 48, in order to have all of the footage covered, Katie would need to buy (at least) 5 rolls.
Hope I helped and please give me brainliest!
Please repost a clear picture so I can help, Thanks.
If interpreted as shown, the order is shown in the lines following
1+sin(x)/1-sin(x)-1-sin(x)/1+sin(x)
=1 + ((sin(x))/1) - sin(x) -1 - (sin(x)/1) + sin(x)
which is completely meaningless for the purpose of this question.
The left-hand side is
common denominator is (1-sin(x))(1+sin(x)), so
using a^2-b^2=(a+b)(a-b)
