Edward rewrote the product of two rational expressions to show the multiplication of the numerators and denominators. His work is shown below. (5y/9)(x+3/4x) (5y)(x+3)/(9)(4x) What is the product of the rational expressions? A: 5xy+3/36x B: 5xy+15y/36x C: 5y+x+3/4x+9 D: 15xy/36x Need help!!

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.

hope it

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
