(x+y+2)(y+1)

a)y^2+4xy+2
b)xy+4y+x+2
c)y+x+y+2
d)y^2+xy+x+3y+2

answ9x x 3=

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
