URGENT PLEASE HELP ME, ITS DUE IN A HOUR

Olegator [25]

Answer:

Area of gray region = $8x^2+8x-7$

Step-by-step explanation:

The area covered by the furniture can be subtracted from the total area of the room to calculate the area of the gray region.

<em>Total</em> area of the room: $13x^2+7x-2$

Area taken up by furniture: $5x^2-x+5$

Area of gray region = total area of the room - area taken up by furniture

Area of gray region = $13x^2+7x-2-(5x^2-x+5)$

Remember to distribute the negative sign:

Area of gray region = $13x^2+7x-2-5x^2+x-5$

Combine like terms:

Area of gray region = $8x^2+8x-7$

If a+b+c=16 and a^2+b^2+c^2=90 then find the value a^3+b^3+c^3-3abc

grin007 [14]

$(a+b+c)^2=a^2+b^2+c^2+2(ab+bc+ca)\\(16)^2=90+2(ab+bc+ca)\\256-90=2(ab+bc+ca)\\166/2=ab+bc+ca\\83=ab+bc+ca\\a^3-b^3-c^3-3abc=(a+b+c)(a^2+b^2+c^2-ab-bc-ca)\\(a+b+c)(a^2+b^2+c^2-(ab+bc+ca))\\16(90-(83))\\16(7)\\=112$
