xy - -4x²
Step-by-step explanation:
(2x - 3y)(4x -y)
2x( 4x -y) -3x( 4x - y)
8x² - 2xy - 12x² + 3xy
8x²- 12x²- 2xy + 3xy
-4x² + xy
xy - -4x²

Answer:
a and b.
Step-by-step explanation:
I’ll explain by giving an example.
Let’s say that: a=3;b=4;c=5; => they all are consecutive -> their sum is 12.
=> if we use a) n=3 => 3*n+3=3*3+3=12 => correct.
b) n+(n+1)+(n+2)= 3+4+5=12=> correct.
c)n+2n+3n=3+6+9=18=>incorrect.
d)3n=3*3=9=>incorrect.
Five thousand six hundred and twenty one divided by twenty three equals a repeated number.
