Jim has calculated the area of a rectangle to be x3 + x2 + x + 1. if the width of the rectangle is x + 1, then its length is

x^2 + 1

Step-by-step explanation:

Since area = width*length, we need to divide x^3 + x^2 +x + 1 by x + 1 using long division. Since x+1 is a factor of the numerator the fraction simplifies to x^2 + 1

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

70.30
