Rewrite each expression as a polynomial in standard form: (2x^2 − x^3 − 9x +1) − (x^3 +7x − 3x^2 +1)
Vitek1552 [10]

Answer:

Polynomial in standard form will be -2x^3+5x^2-16x

Step-by-step explanation:

We have given polynomial 2x^2-x^3-9x+1-(x^3+7x-3x^2+1)

We have to write this polynomial in standard form

For writing in standard form we have to first subtract the polynomial and then rearrange the order

So 2x^2-x^3-9x+1-(x^3+7x-3x^2+1)=2x^2-x^3-9x+1-x^3-7x+3x^2-1=-2x^3+5x^2-16x

So polynomial in standard form will be -2x^3+5x^2-16x

Please show work. What is the volume of the figure?
Alenkinab [10]

Answer:

Volume = 288 in.³

Step-by-step explanation:

Volume of the solid = volume of the cube + volume of the square pyramid

V = a³ + ⅓*a²*h

a = 6 in.

h = 12 - 6 = 6 in.

Plug in the values into the volume formula

Volume = 6³ + ⅓*6²*6

Volume = 216 + 72

Volume = 288 in.³
