Answer:
yes because |x+y|=|x|+|y| is just the same equation just splitting the numbers
They both are the same absolute value equation
Step-by-step explanation:
|x+y|=|x|+|y|
x+y=|x|+|y|
x+y=x+y
You should know that:
(a+b)(a+b)(a+b)
=a(a+b)(a+b)+b(a+b)(a+b)
=a(a²+2ab+b²)+b(a²+2ab+b²)
=a³+2a²b+ab²+a²b+2ab²+b³
=a³+3a²b+3ab²+b³
-----------------
If a=5x and b=-4y
(5x+(-4y))³
=(5x-4y)³
=(5x)³+3(5x)²(-4y)+3(5x)(-4y)²+(-4y)³
=125x³+3(25x²)(-4y)+15x(16y²)-64y³
=125x³+75x²(-4y)+240xy²-64y³
=125x³-300x²y+240xy²-64y³
Answer:
9
Step-by-step explanation:
There would be 9 because 7 goes into 66 9 times
the answer would be 10/21
