Answer:
the third one, the one that says 0.625
Step-by-step explanation:
A common denominator for 2/5 is 4/10 because 2/5 times the denominator and numerator by 2 is 4/10
And the common denominator for 1/2 is 5/10 because 1/2 times the denominator and numerator by 5 is 5/10
So the equivalent denominators for both fractions is 4/10 and 5/10
(4x² + 2y)(3x + y²<span>) =
12x</span>³ + 4x²y² + 6xy + 2y³
<span>The coefficient of xy is 6</span>
3(2)+2(3)=12 <<<< is the answer! :)
