Mathematics
1 answer:
laiz [17]3 years ago

Answer:

<h2>BC = 25</h2>

Step-by-step explanation:

It's an isosceles triangle (congruent angles ∠C ≅ ∠B).

Therefore AC = AB.

We have the equation:

4x+1=2x+23        <em>subtract 1 from both sides</em>

4x=2x+22       <em>subtract 2x from both sides</em>

2x=22          <em>divide both sides by 2</em>

x=11

Substitute the value of <em>x</em> to the expression BC = 3x - 8:

BC = 3(11) - 8=33-8=25

Please help me im stick on this algebra 2 question
timama [110]
Hi I’m Charles from the University of Alaska Mathematics Department. I have a degree in dentistry, chemistry, zoology, algebra, geometry and finally literature. Anyways I was very interested by your question so I took a look and saw that this indeed is a hard question. However when I look at it it doesnt look to bad but it could pose to be quite difficult. So assuming from the question I could tell that you need to define the square root untill you hit the zero degree of -2. But you could instead solve for negative externalities of the equations and then use the Calvin formula to solve this question. So ultimately the answer is A. I hope this helps!
