Hi there!
First, we need to determine the volume.
1/2 × 2 × 7/2 = 7/2 in cubed
3.5 cubes with sidelengths of 1in can fit in, since both units are three dimensional and 7/2 ÷ 1 = 3.5
7 cubes with sidelengths of 1/2 can fit because 7/2 ÷ 1/2 = 7
Hope this helps!
A - price of the senior citizen ticket
b - price of the student ticket
{4a+5b=102
{7a+5b=126
3a=24 → a=8
5b=102-32
5b=70
b=14
price of the senior citizen ticket is $8
price of the student ticket is $14
4x^2(3x^2-8x+6)
(4*3)(x^(2+2))+(4*-8)(x^(2+1))+(4*6)(x^(2+0))
12x^4-32x^3+24x^2
