A rectangle has an area of 4(x + 3) square units. x + 3= width, 4=length Use the distributive property to write an equivalent expression for the rectangle’s area. Answer _______​


  1. Answer: 4x+12=4x+12 or 4x+12=4(x+3)

    Step-by-step explanation:

    1. (x+3)(4)=4(x+3)  *because length x width=area
    2. Distribute 4 into the parenthesis
    3. 4x+12=4(x+3)
    4. you can go even further
    5. 4x+12=4x+12

    Hope this helps!

  2. Answer:

    4x + 12

    Step-by-step explanation:

    4*x + 4*3 = 4x + 12

    • Notice what has happened. The plus sign remains.
    • The 4 multiplies by both the x and the 3

    That’s as far as you can take the problem. You cannot reduce it any further or combine it in any way. The reason is that the x has a 4 in front of it and the 12 has no x.

    When those terms are separated by a plus or minus sign, the terms are not the same. Unlike terms cannot be combined.
