I believe the answer is 9.
(x+5) represents each side of a square. Since all sides of a square are equal, we know that all sides are (x+5).
Base x height = (x+5)(x+5)
Which is x^2+10x+25!
The parabola opens down, since the 'a' value of the equation is a negative value.
Hey there!
Here's your answer: m<2=114.52 degrees
Here's how I got it: we know that a linear pair of angles is supplementary, aka the sum of the angles is 180 degrees.
you would add 18x-1 and 23x+7 together to equal 180 and solve for x.
then, you would substitute x for 4.24 (rounded) into 23x+17
23(4.24)+17=114.52
Hope this helps!
<em>The regular price was $110</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em />
<em>60% .......... $66</em>
<em>100% ..........$ x</em>
<em>x = 100×66/60</em>
<em>= 6600/60</em>
<em>= $ 110</em>

<em>Good luck !</em>
