Multiplying binomials (×+2) (×-9)

Mathematics
1 answer:
musickatia [10]4 years ago

Answer:

x² -7x -18

Step-by-step explanation:

In algebra, a binomial consists solely of a sum or subtraction of two monomials.  

To solve the multiplication of two binomials we have to multiply term by term and then simplify common terms.

(x + 2)(x - 9) = x(x) + x(-9) +2(x) + 2(-9) = x² -9x + 2x -18 = x² -7x - 18

Dmitriy789 [7]

Answer:

The retail price is: $39

Step-by-step explanation:

The original price is $50. With a markdown of 22$, what is the new or retail price?

$50 - (50 * 22%) =

50 - (50 * .22) =

50 - 11 = $39

Proof:

11/50 = .22 or 22%
