A. find the area<br><br>b. find the perimeter​
Allushta [10]

Answer:

Area= 4y^2 + 14y + 12

Perimeter = 10y + 16

Step-by-step explanation:

Area of a reactangle = length × width

= (4y+6) × (y+2)

= 4y^2 + 6y + 8y + 12

= 4y^2 + 14y + 12

Perimeter of a rectangle = 2 × (a +b)

= 2 × ( 4y + 6 + y+ 2)

= 2 × ( 5y + 8)

= 10y + 16

Can someone explain end behaviors and answer this question?
Luda [366]

Answer:

End behaviors are basically what the function looks like as it ends.

as x approaches positive infinity (the sideways 8) its increasing.

for the picture i believe the answer is C.

Step-by-step explanation:

basically because when you look at where the negatives are they continue which means it’s -infinity and so as the function approaches -infinity it’s x —> positive infinity and same thing for as x approaches positive infinity.
