Answer:
The center is (20, 0.05) radius = 9
Step-by-step explanation:
The center is (20, 0.05) radius = 9
from the general form of the equation:
(x - h)^2 + (y - k)^2 = r^2
we see that r^2 = 81
so r = 9
2x²-3xy-2y²-2x-11y-12
Write -3xy as a difference
2x²+xy-4xy-2y²-2x-11y-12
write -2x as a difference
2x²+xy-4xy-2y²+4x-6x-11y-12
Write -11y as a difference
2x²+xy-4xy-2y²+4x-6x-8y-3y-12
Factor out 2x from the expression
2x×(x-2y-3)+xy-2y²+4x-8y-3y-12
Factor out y from the expression
2x×(x-2y-3)+y×(x-2y-3)+4x-8y-12
Factor out 4 from the expression
2x×(x-2y-3)+y×(x-2y-3)+4(x-2y-3)
Factor out x-2y-3 from the expression
Answer: (x-2y-3)x(2x+y+4)

Answer:
<em>It takes them 1.875 hours.</em>
<em></em>
<em>Step-by-step explanation:</em>
<em></em>
<em>Here, the job is cleaning the house.</em>
<em></em>
<em>Mom does 1 job in 3 hours.</em>
<em></em>
<em>In 1 hour, mom does 1/3 of the job.</em>
<em></em>
<em>Dad does 1 job in 5 hours.</em>
<em></em>
<em>In 1 hour, dad does 1/5 of the job.</em>
<em></em>
<em>Mom and dad working together do the job in x hours.</em>
<em></em>
<em>In 1 hour, mom and dad together do 1/x of the job.</em>
<em></em>
<em>1/3 + 1/5 = 1/x</em>
<em></em>
<em>5/15 + 3/15 = 1/x</em>
<em></em>
<em>8/15 = 1/x</em>
<em></em>
<em>8x = 15</em>
<em></em>
<em>x = 15/8 = 1.875</em>
<em></em>
<em>Answer: It takes them 1.875 hours.</em>
