You said that (xy) = 16, and (x+y) = 4 .
From the second equation you can get [ x = 4 - y ],
then substitude that for 'x' in the first equation, and
finally, rearrange the first equation to read
<u>x² - 4x + 16 = 0</u>
Don't even try to factor that quadratic equation. Go straight
to the quadratic formula, and the two solutions you find are ...
<em>x = 2 + i 2√3</em>
and
<em>x = 2 - i 2√3</em> .
Those are the two number that do what you want.
There are no <u>real</u> numbers that can do it.
I pretty sure your answer is c I may be wrong.
Hello there, and thank you for posting your question here on brainly.
The diameter of a circle is how long it is from the left side of the circle to the right side.
The radius of a circle is the length of either the left or the right side to the middle.
So, the radius is half of a radius.
You can divide the known diameter by 2 to get your answer.
Its diameter is 25.
Divide 25 by 2.
25 / 2 = 12.5
Its radius is 12.5 in.
That would be answer choice A.
Hope this helped!! ☺♥
This answer would be A hope this helps
