Answer:
x^3 + x^2 + 4x - 20.
Step-by-step explanation:
I have assumed there is a + between the 3x and the 10.
f(x) * g(x)
= (x^2 + 3x + 10)(x - 2)
= x^3 + 3x^2 + 10x - 2x^2 - 6x - 20
= x^3 + x^2 + 4x - 20.
The 4-dimensional volume<span> of a polyhedral </span>pyramid<span> is 1/4 of the </span>volume<span> of the base polyhedron times its perpendicular height, compared to the area of a triangle being 1/2 the length of the base times the height and the </span>volume<span> of a </span>pyramid<span> being 1/3 the area of the base times the height.</span>
Step-by-step explanation:
5B+4F= $30.76
×3
15B+12F= $92.28
----------------------------
8B+6F= $48.28
×2
16B+12F= $96.56
----------------------------
Cost of one burger:
$97.56-$92.28= $4.28 (final ans)
Cost of one fries:
$30.76-5($4.28)= $9.36 (for 5 fries)
$9.36÷5= $1.87 (final ans)
28, because when you divide you get about 28. good luck!
