A rectangle has a height of x+4 and a width of x2+3x+2 Express the area of the entire rectangle
Your answer should be a polynomial in standard form.

area=x^2+3x+2 * x+4

=x^3+3x^2+2x+4x^2+12x+8

=x^3+7x^2+14x+8

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
