Question

Help, write an expression in the simplest form that represents the area (in square feet) of the banner.

Answer 1

Answer:

3 (3 + x) is equal to the banner

Answer 2

Answer:

3x+9 ft²

Step-by-step explanation:

The formula for the area of a rectangle is height × length

The height of the banner is 3, and the length is 3+x

So, you would do 3(3+x)= 3×3+3x= 3x+9

Therefore, the answer would be 3x+9 ft²
