Answer:
(3x^2-5x-5)/(x^2+x) <--- answer
Step-by-step explanation:
3x/(x+1) - 5/x = (3x^2 - 5(x+1) )/[ x(x+1) ]
= (3x^2 - 5x - 5)/(x^2 + x)
<em>Answer:</em>
<em>The unknown angles are 45 and 63</em>
<em>Step-by-step explanation:</em>
<em>5x + 7x + 72 = 180 (angle sum property)</em>
<em>12x + 72 = 180</em>
<em>12x = 180 - 72</em>
<em>12x = 108</em>
<em>x = 108/12</em>
<em>x = 9 </em>
<em />
<em>Therefore, 5x = 5*9 = 45</em>
<em> 7x = 7*9 = 63</em>
A: Deena subtracted 25, instead of adding it.
B: 9x - 25 = 88.
C: no idea
If she has 7 stacks of 7 dimes:
