Answer:
<h2>1/2</h2>
Step-by-step explanation:
there are 2 corners that are blue out of 4
2/4 is the same as 1/2
Answer:
(2x - 5y)²
(2x - 5y)(2x - 5y)
2x(2x - 5y) - 5y(2x - 5y)
2x(2x) - 2x(5y) - 5y(2x) + 5y(5y)
4x² - 10xy - 10xy + 25y²
4x² - 20y + 25y²
The answer is B.
Step-by-step explanation:
Is this rearranging of equation??
-n+sx=n-a
sx=2n-a
x=2n-a/s
