<u><em>The picture of the question in the attached figure</em></u>
we know that
The area on the side of the house that is NOT covered by the light is equal to the area of semicircle minus the area covered by a spotlight on the side of a house
Find the area of the semicircle
The area of a semicircle is equal to
we have
substitute
Find the difference
x^2 - 8 ) x^4 +- 36 ( x^2 + 8
x4 - 8x^2
8x^2 + 36
8 x^2 - 64
Subtract 36 - - 64 = 100 Answer
Answer:
The answer would be 22/12 or 1 and 11/12
Step-by-step explanation:
1/2+2/3+3/4
First get common denominators so you have a denominator of 12 so 6/12+8/12+9/12
Add those together and you get 23/12 but you have to subtract one because that's what the problem says so you get 22/12
The answer is the fourth line because it starts with 1 and then you have to subtract 3 from 1 (1-3) and you get -2
