I'm doing a portfolio in math rn and i need help, fast please. Lesson 11: Solving Inequalities by Multiplying or Dividing. Grade: 7
Versatile Distributive Property Portfolio
Directions: Your family is having a day without technology. No calculators, cell
phones, or computers are allowed. You have a math assignment to finish, so it’s
time to put the computation properties you have learned to good use. This is your
chance to see how versatile the Distributive Property is and how it can make your
life easier!
Thanks to the Distributive Property, there are two different ways of computing
3(4 5 6) + + :
-Calculation with Distribution:-
3(4 + 5 + 6) =
3 × 4 + 3 × 5 + 3 × 6 =
12 + 15 + 18 =
45
-Calculation without Distribution-
3(4 + 5 + 6) =
3(15) =
45
You will get the same answer regardless of which method you use.
In each of the following situations, show all steps for both ways of calculating with
the Distributive Property. In some cases, you will find it easier to distribute the
multiplication over each of the addends before adding. In the other cases, you may
think it helps to not distribute and to add the numbers before multiplying.
Remember, showing your work is an important part of this portfolio.
Vote for which way you think is more efficient and explain why.

  1. Geeze why dont people answer any of our questions??? It's like we're just asking so that other kids will have the answer in the far away future😭😭

    With distribution
    12(12+12)=
    144+144=
    288

    Without distribution
    12(12+12)=
    12(24)=
    288

    That was the third
    the first....
    W dist
    0.2 (2.50 + 4.95 + 6.00) =
    0.2 * 2.50 + 0.2 * 4.95 + 0.2 * 6.00 =
    1.345 + 1.345 =
    2.69

    W/o dist
    0.2 (2.50 + 4.95 + 6.00)=
    0.2 (13.45)=
    2.69

    The second
    W dist
    .06 (2.50 + 8.75 + 3.00 + 10.25)=
    .06 * 2.50 + 06 * 8.75 + 06 * 3.00 + 06 * 10.25 =
    0.735 + 0.735=
    1.47

    W/o dist
    .06 (2.50 + 8.75 + 3.00 + 10.25) =
    .06 (24.50)=
    1.47

    Hope this helps that's as far as I've reached sorry

  3. with Distribution 24.50+8.75+3.00+10.25=24.50
    24.50*1.06=25.97
    25.97-24.50=1.47
    without Distribution
    .06+(2.60)+.06(8.25)+.06(3.00)+.06(10.25)
    =24.50 then subtract 25.97-24.50=1.47
