I also don't know the answer to this question
<em>Answer:</em>
<em>x ≅ 79.1</em>
<em>Step-by-step explanation:</em>
<em>10log(4x) = 25 </em>
<em>2log(4x) = 5 </em>
<em>log((4x)²) = 5 </em>
<em>(4x)² = 10⁵ </em>
<em>16x² = 100,000 </em>
<em>x² = 6,250 </em>
<em>x ≅ 79.1</em>
1 minute = 60 seconds
240 minute = 240 × 60 = 14400 seconds
<h2><u>
240 minute = 14400 seconds</u></h2><h2><u>

3-5(2x+1) < 10
3-10x-5<10
-10x-2<10
-2<10+10x
-12<10x
-1.2x>-1.2
