The answer could be 45 but I'm not entirely sure
Answer:
the third one is hard to see i think its 77 so the answer is 54.75
Step-by-step explanation:
(x+2)(1-x)=-4
subtract 2 from both sides: x(1-x)=2
simplify:x-2x=2
subtract: -x=2
switch the negatives
x=-2
To find the length of a side of a square fins the square root of the area.
Area = 200 cm^2
Side = √200
Side = 10√2 (Exact length)
or 14.142 cm's ( round the decimal answer as needed.)
It would be 56/177. If you need any question how I got that answer, ask me.. :)
