What is the surface area of the rectangular prism below 7, 7, 14

Julli [10]

Answer:

Surface Area A = 490 cm²

Step-by-step explanation:

Surface area of a prism A = 2(w l +h l + h w)

where l = length

w = width

h = height

l = 7 cm; w = 7 cm ; h = 14 cm

Surface Area = 2 { ( 7 × 7) + ( 14 × 7) + ( 14 × 7)}

A = 2 { 49 + 98 + 98}

A = 2 × 245

A = 490 cm²

pogonyaev

Answer:

$-5x^2+5x+1$

Step-by-step explanation:

To simplify polynomials, find the like terms which look and sound the same then combine the coefficients of each to simplify.

$(2x^2-9x+3)+(-7x^2+4x-2)\\2x^2-7x^2-9x+4x+3-2\\-5x^2+5x+1$
