Answer:

  500

Step-by-step explanation:

Mental calculation often makes use of factoring and cancelling of factors. To the greatest possible extent, multiplying or dividing by powers of 2, 5 and 10 are also used.

  \dfrac{110568}{220}-\dfrac{568}{220}=\dfrac{110568-568}{220}=\dfrac{110000}{220}\\\\=\dfrac{110}{220}\cdot1000=\dfrac{1}{2}\cdot1000=\boxed{500}

Suppose X and Y represent two different school populations where X > Y and X and Y must be greater than 0. Which of the follo
Stells [14]

Answer:(X+Y)²

X²+Y² would be greater than X²-Y² since addition gives a greater result than subtraction.

X²+Y² would be greater than 2(X+Y); this is because 2(X+Y) = 2X+2Y, which will be less than X²+Y², since X>Y.

(X+Y)² = (X+Y)(X+Y). This can be simplified using the distributive property:

X(X)+X(Y)+Y(X)+Y(Y) = X²+XY+YX+Y² = X²+2XY+Y². This is greater than X²+Y².
