Answer:

x/y = 88/7

Step-by-step explanation:

x+y=19

x+3y=12y+5

First rewrite second equation as:

x +3y-12y = 5

Combine like terms:

x-9y = 5

Now you have:

x+y=19

x-9y = 5

Elimination method Subtract 2 equations:

10y = 14 Divide both sides by 10

y = 14/10 = 7/5

Plug in y in any given equation and calculate x:

x+ 7/5 = 19 Subtract 7/5 from 19

x = 88/5 = 17 3/5

x/y = 88/5 : 7/5

The polynomials P(x)=x^3−x−2 and Q(x)=x^2+2x+1 are multiplied and the result is completely simplified.

GarryVolchara [31]

Answer:

C. 2x^4; E. -5x

Step-by-step explanation:

P(x) = x^3 − x − 2 and Q(x) = x^2 + 2x + 1

P(x) * Q(x) = (x^3 − x − 2)(x^2 + 2x + 1) =

= x^5 + 2x^4 + x^3 - x^3 - 2x^2 - x - 2x^2 - 4x - 2

= x^5 + 2x^4 - 4x^2 - 5x - 2

Answer: C. 2x^4; E. -5x

How do you factor by finding the common monomial factor?

klemol [59]

To find the greatest common factor of two monomials, first find the prime factorization of each monomial, including all the variables (and a – factor if necessary). Then take the product of all common factors. First, find the prime factorization of each monomial. So, the GCF is 3 p 2 r 3 .
