<em>The answer is 58.</em>
<em />
<em />
<em />
<em>First, we need to find</em><em> "x"</em><em>, being the </em><em>number.</em>
<em />
- <em>13+45=58</em>
- <em>X=58</em>
<em>----------------------------------------------------------------------------------------------------------</em>
<h3><em>How did we get 58 though?</em></h3><h3><em /></h3><h3><em>----------Steps---------</em></h3>
- <em>Add</em><em> </em><em> 3+5</em>
- <em>3+5=8</em>
- <em>Then </em><em>add 1+4</em>
- <em>1+4=5</em>
<em />
<em />
<em>Therefore, the answer is </em><em>58.</em>
<em>X=58</em>

D = {0,1,-1,2,-2,3,-3,4,-4,...}

<span>F = {12,14,16,18} </span>
<span>Finding an intersection of sets means listing the elements that are in both sets. </span>
<span>Finding a union of sets means listing all elements that are in either set. </span>
<span>With that in mind, </span>
<span>1. D intersect E = E because every element of E is a whole number, so it is in D also. </span>
<span>2. D intersect F = F because every element of F is a whole number, so it is in D also. </span>
<span>3. D intersect (E intersect F) First we find E intersect F = {16} because only 16 appears in E and F. Then, since 16 is also in D, D intersect (E intersect F) = {16} </span>
<span>4. We've already established that D contains everything in E and F. So when we take a union of (E intersect F) with D, we get all of D. </span>
<span>5. E union F = {1,4,9,12,14,16,18,25,36,49,64,81} because these are all the elements that are in either E or F. Intersecting with D doesn't change this list, since all are whole numbers.</span>
The variable c is equal to 13
