x => Hamburgers

y => Hot dogs

x + y = 26

3.5x + 2y = 70

-2x - 2y = -52

3.5x + 2y = 70

1.5x = 18

x = 18 / 1.5 = 12

y = 26 - 12 = 14

Multiply (2x-5)(3x^2-4x+2)

fgiga [73]

Answer:

$\large\boxed{(2x-5)(3x^2-4x+2)=6x^3-23x^2+24x-10}$

Step-by-step explanation:

$\text{Use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(2x-5)(3x^2-4x+2)\\\\=(2x)(3x^2)+(2x)(-4x)+(2x)(2)+(-5)(3x^2)+(-5)(-4x)+(-5)(2)\\\\=6x^3-8x^2+4x-15x^2+20x-10\\\\\text{combine like terms}\\\\=6x^3+(-8x^2-15x^2)+(4x+20x)-10\\\\=6x^3-23x^2+24x-10$
