X^2-8x+16 divided by ax-4x numerator

Vedmedyk [2.9K]

Answer:

Given:

1). $x^2-8x+16$ divided by $x-4$

⇒ $\frac{x^2-8x+16}{x-4}$

⇒ $\frac{x^2-2\times x\times 4+4^2}{x-4}$

By factorising numerator by using identity, $(a-b)^2=a^2-2\times a \times b +b^2$

⇒ $\frac{(x-4)^2}{x-4}$

⇒ $\frac{(x-4)\times(x-4)}{x-4}$

⇒ $x-4$ {Answer}

2). $3x^2y$ divided by $6xy^2$

⇒ $\frac{3x^2y}{6xy^2}$

⇒ $\frac{3\times x\times x\times y}{6\times x\times y\times y}$

⇒ $\frac{x}{2y}$ { Answer}

Poppy felix and Alex sell 700 raffle tickets between them.

prohojiy [21]

First 700-25=675

Poppy= 2F (F as in Felix, since she sells twice as much)
Alex = (Now equals 2F as well, cus we already took away the 25)
And well.... Felix is just felix so add that all up

F+F+F+F+F=5F

675/5=135!
Now according to that 135 is how many felix sold

Felix=135
Poppy=270
Alex=295
