Answer:
0.785 m
Step-by-step explanation:
(4-2x)(6-2x)x = Volume
Volume = 4x³ - 20x² + 24x
Max volume: dV/dx = 0
dV/dx = 12x² - 40x + 24 = 0
3x² - 8x + 6 = 0
x = 2.54858377, 0.784749563
Max when d²V/dx² < 0
d²V/dx² = 6x - 8
At x = 0.784749563
6x - 8 = -3.29 < 0
Draw 2 shapes + 5 shapes = 7 shapes

Answer:
$0.45
Step-by-step explanation:
1 tin of beans-> $1.55÷3=$0.31
3 tins of beans-> $0.31×3=$0.93
4 tins of tomatoes-> $2.73-$0.93=$1.80
1 tin of tomatoes->$1.80÷4=$0.45
