11. Rebecca is building a pen for her rabbits against the side of her house. The polynomial 4n+ 8 represents the length and the polynomial 2n = 6
represents the width
2n +6
What polynomial represents the perimeter
of the entire pen?
a
4n+8
m и с от
b. What polynomial represents the perimeter
of the pen NOT including the side of the house.
Ok

a. 12n + 28

b. 8n + 20

i think this could be a possible answer (1 / 84) -1

good luck! : d

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
