Correct answer is A.

(x^2+4x-3)(2x^2+x+6)
\\=x^2(2x^2+x+6)+4x(2x^2+x+6)-3(2x^2+x+6)
\\=2x^4+x^3+6x^2+8x^3+4x^2+24x-6x^2-3x-18
\\=2x^4+x^3+8x^3+6x^2+4x^2-6x^2+24x-3x-18

use  simple ratio, 3:2 (3 pepperoni for every 2 cheese)
to make the ratio bigger, we substitute the "3" pepperoni for "15" pepperoni. then take the new amount, 15/3 original, you get 5. then multiply the 2 original cheese pizzas by that 5, and you get 10 cheese pizza's.

What two numbers multiplies to 36 and add to negative 21
anastassius [24]
Factor 36 and add them, make sure both are negatie
1+36=37, nope
2+18=20 nope
3+12=15,nope
4+9=13, nope
6+6=12, nope

the closest one is 20

I hope you meant adds to -20, because if you did, then answer is -2 and -18

if you did mean 36 and adds to -21, then the numbers are \frac{-21-3 \sqrt{33} }{2} and \frac{-21+3 \sqrt{33} }{2}, aprox -19.1168 and  -1.8831

This question overall depends on a continuously changing factor.

There are many houses in this world that have an area of less than 100 m^2, while many others have up to 700, 800, or even 1000 m^2 of land. Your question is impossible to calculate because of the massive amount of houses in this world. If you want a good estimate, say around 0.9 to 1.8 billion.
