Use FOIL to multiply binomials by multiplying each term in the first binomial by the terms in the second binomial.
(4x - 3)(x + 5)
4x^2+20x-3x-15
Now combine like terms.
answer : 4x^2+17x-15
<span>B, (~1, 4) Sorry I replied late! I had other people with questions.</span>
2 x
----- = ------
3 15
cross multiply
(3)(x) = (15)(2)
3x = 30
x = 30/3
x = 10
so 2/3 = 10/15.......notice how these are equivalent fractions....that is because proportions are nothing but equivalent fractions
