Answer:

Step-by-step explanation:

e. simplify 3x+9y+2x

here combine like terms. 3x+2x=5x

then add 9y from question. so answer is 5x+9y

f. simplify 7(3x+y)

Expand the form using distributive property.

7(3x+y)= 7(3x)+7(y)

          =   21x +7y

g. Factor: 12x+8y

 12x=2*2*3*x    and 8y= 2*2*2*y

take gcd= 2*2=4

so 12x+8y= 4(3x+2y)
