Your answer would be: 7(c-70)
Step 1:<em> Combine like terms</em>:
- 10(<em>- 5c </em>+ <em>4c </em>+ 7) - 3c
-10(<em>- c </em>+ 7) - 3c
Step 2: <em>Distribute</em>:
<em>-10 (-c - 7) </em>- 3c
<em>10c - 70 </em>- 3c
Step 3: <em>Combine like terms:</em>
<em>10c </em>- 70 <em>- 3c</em>
<em>7c</em> - 70
Step four: <em>Common factor</em>
<u><em>Factor by grouping: </em></u>
- 10(− 5c + 4c + 7) − 3c
7(c-10)
