Step-by-step explanation: 5 20 21 02

There are 5 areas to calculate

Top = LW = (20)(17)

Bottom = LW = (20)(15)

Back = LW = (20)(8)

2 Triangular Ends = One square = LW = (8)(15)

Total Surface Area = (20)(17) + (20)(15) + (20)(8) + (8)(15)

= (20)(17 + 15 + 8) + (8)(15)

= (20)(40) + (8)(15)

= 800 + 120

= 920 ft²

What is (2+y)³ written out? 8 + 12y + 6y² + y³ 6 + 8y + 4y² + y³

AveGali [126]

$\boxed{(2+y)^3-cube\ the\ sum\ of\ the\ numbers\ 2\ and\ y}$

$Use:\ (a+b)^3=(a+b)(a+b)(a+b)=a^3+3a^2b+3ab^2+b^3\\----------------------------\\(2+y)^3=2^3+3\cdot2^2\cdot y+3\cdot2\cdot y^2+y^3=8+3\cdot4y+6y^2+y^3\\\\=8+12y+6y^2+y^3\\========================================$

$8+12y+6y^2+6y^3+8y+4y^2+y^3\\=8+(12y+8y)+(6y^2+4y^2)+(6y^3+y^3)\\=8+20y+10y^2+7y^3$
