i have been having trouble with these type of equations. I don’t understand how you solve them. I copied an answer from one of my HW assignments in which they have the step by step to get your answer, but again i don’t really understand how they are able to get to that conclusion. Im not sure if they multiple, add, subtract, etc. I think the (x) is where i really get confused, for example (3x+5) most of the time it equals to a higher number and im not sure what type of way you’re supposed to solve these type of problems. If someone can help me understand in a detailed way how you get the answers for these equations it’d be so much helpful!! if mLABD = 84, what are mL ABC and LDBC?DBanuieſ(4x+4).Buse the fact that the two angles formLABD and the angle addition postulateto write an equation to solve for x.

For a certain company, the cost for producing a items is 40x + 300 and the revenue for selling x items is 80x – 0.5x². The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit! Part a: Set up an expression for the profit from producing and selling x items. We assume that the company sells all of the items that it produces. (Hint: it is a quadratic polynomial.) Part b: Find two values of that will create a profit of $50. The field below accepts a list of numbers or formulas separated by semicolons (e.g. 2; 4; 6 or x + 1; x – 1). The order of the list does not matter. To enter va , type sqrt(a).

Hello, I have been stuck on this question for a while now. I believe I did all the steps right thus far if I did not make a mistake somewhere down the line, I have not been able to find a way to know what A=? and what B=? could anyone spot a mistake that I could have made down the line or what might be my next step to finally finding what A and B are equal to? Thanks, you!
Please answer and solve asap
