<h2>Answer:</h2>

<em><u>The answer is actually, "C"</u></em>

<h2 /><h2><em>Step-by-step explanation:</em></h2>

<em><u>I mean to offence to the other person, but sadly I must prove them wrong.</u></em>

<em><u>Let's start by finding the area of the triangles.</u></em>

<h2><em>Triangles:</em></h2>

Area = 1/2 · base · height
= 1/2 · 4 · 3
= 1/2 · 12
= 6

<em><u>There are two triangle faces with an area of 6 square units.</u></em>

<em><u>So, we add it twice.</u></em>

<h2><em>Left rectangle:</em></h2>

Area = base · height
= 3 · 10
= 30

<h2><em>Center rectangle:</em></h2>

Area = base · height
= 4 · 10
= 40

<h2><em>Right rectangle:</em></h2>

Area = base · height
= 5 · 10
= 50

Finally, we add the area of them all.

<h2><em>Expression:</em></h2>

6 + 6 + 30 + 40 +50.

Paraphin [41]

So if 6 dozen cookies needs 3/4 cup of sugar, and we need to know how much sugar is needed to make 4 dozen, then find how much of 6 dozen 4 dozen is.

To do this, put it as a fraction:

4 dozen / 6 dozen, or 4/6, which is 2/3.

Since conveniently it calls for 3/4 cup of sugar, we can multiply that by 2/3, and we'll get 6/12, or 1/2.

So 1/2 cup of sugar is needed for 4 dozen cookies.

Show the ratios are equivalent by simplifying any 4 of them.

aliya0001 [1]

When simplified all of them equal 3/1. They are asking you to just chose 4 of them. Hope that helps!
