(X^3+1)dividend (x-1)
bazaltina [42]

x^3=x\cdot x^2 and x^2(x-1)=x^3-x^2. So we have a remainder of

(x^3+1)-(x^3-x^2)=x^2+1

x^2=x\cdot x and x(x-1)=x^2-x. Subtracting this from the previous remainder gives a new remainder

(x^2+1)-(x^2-x)=x+1

x=x\cdot1 and 1(x-1)=x-1. Subtracting this from the previous remainder gives a new one of

(x+1)-(x-1)=2

and we're done since 2 does not divide x. So we have

\dfrac{x^3+1}{x-1}=x^2+x+1+\dfrac2{x-1}

Help with the picture
True [87]

Answer:

The first question is 9.

The second is 36.

The third is 8 1/2

Step-by-step explanation:

For the first one, there are 8 cubes plus the two halves, which equal 1 so 8 plus 1 equals 9.

The second one is 9 divided by a quarter which is 1/4, 9 divided by 1/4 equals 36.

For the third, length times witdth times height equals volume. So then (you don’t have to do it in order but) 2 times 1 times 4 1/4 equals 8 1/2.
