Answer:

Length = 5x + 3

Width = x  +1

Step-by-step explanation:

Given

Area = 5x^2 + 8x + 3

Required

Determine the dimensions

To do this, we simply factorize the given expression.

Area = 5x^2 + 8x + 3

Expand

Area = 5x^2 + 5x +3x+ 3

Factorize

Area = 5x(x + 1) +3(x+ 1)

Factor out x + 1

Area = (5x +3) (x+ 1)

Area is calculated as:

Area = Length * Width

So:

Length = 5x + 3

Width = x  +1

The given is:

1. Ann uses 12 1/4 ounces of peanut butter to make 50 1/2 Sandwiches

2. Ben uses 7 1/4 ounces of peanut butter to make 48 1/2

3. Cal uses 15 1/2 ounces of peanut butter to make 85 1/2 sandwiches

To find whose recipe produces the sandwiches with the most peanut

butter flavor we must find the quantity of butter per sandwich in each

recipe

∵ Ann uses 12.25 ounces of peanut butter to make 50.5 Sandwiches

- Divide the quantity of butter by the number of sandwiches

∵ 12.25 ÷ 50.5 = 0.2426 ounce per sandwich

Ann recipe produces the sandwiches with 0.2426 ounce per sandwich

∵ Ben uses 7.25 ounces of peanut butter to make 48.5 Sandwiches

- Divide the quantity of butter by the number of sandwiches

∵ 7.25 ÷ 48.5 = 0.1495 ounce per sandwich

Ben recipe produces the sandwiches with 0.1495 ounce per sandwich

∵ Cal uses 15.5 ounces of peanut butter to make 85.5 Sandwiches

- Divide the quantity of butter by the number of sandwiches

∵ 15.5 ÷ 85.5 = 0.1813 ounce per sandwich

Cal recipe produces the sandwiches with 0.1813 ounce per sandwich

∵ The greatest quantity of butter per sandwich is 0.2426 ounce

∴ Ann recipe produces the sandwiches with the most peanut

  butter flavor

Ann recipe produces the sandwiches with the most peanut butter flavor
