Step-by-step explanation:

<u>Step 1:  Distribute</u>

<u />(x^2-3x+4)(-2x^2+4x-1)

(x^2*-2x^2)+(x^2*4x)+(x^2*-1)+(-3x*-2x^2)+(-3x*4x)+(-3x*-1)+(4*-2x^2)+(4*4x)+(4*-1)

(-2x^4) + (4x^3)+(-x^2)+(6x^3)+(-12x^2)+(3x)+(-8x^2)+(16x)+(-4)

-2x^4+4x^3+6x^3-x^2-12x^2-8x^2+16x+3x-4

-2x^4+10x^3-21x^2+19x-4

-2x⁴ + 6x³ - 8x² + 4x³ - 12x² + 16x - x² + 3x - 4

-2x⁴ + 10x³ - 21x² + 19x - 4

The volume of a right triangular prism is 72 cubic feet. The height of the prism is 9 feet. The triangular base is an isosceles
Mariulka [41]

Answer:

Step-by-step explanation:

volume = area of base * height = area of base * 9 = 72

-> area of base = 72/9 = 8

let a,b,c be the length of sides of isosceles right triangle base

we have a = b and a*b/2 = 8 ft2

-> a*a/2 = 8ft2

-> a*a = 16

-> a=4ft=b

have c^2 = a^2 + b^2 = 16 +16 = 32

-> c = \sqrt{32} = 5.656 ft

Since i dont know that is DF, i calculate both a,b and c
